## Summary
Nvim 0.11+ uses the builtin `vim.lsp.enable` and `vim.lsp.config` to
enable and configure LSP clients. This adds the new non legacy way of
configuring Nvim with `nvim-lspconfig` according to the upstream
documentation.
Update documentation for Nvim LSP configuration according to
`nvim-lspconfig` and Nvim 0.11+
## Test Plan
Tested locally on macOS with Nvim 0.11.1 and `nvim-lspconfig`
master/[ac1dfbe](ac1dfbe3b6).
## Summary
Refer to the VS Code PR
(https://github.com/astral-sh/ruff-vscode/pull/659) for details on the
change.
This PR changes the following:
1. Add tracing span for both request (request id and method name) and
notification (method name) handler
2. Remove the `RUFF_TRACE` environment variable. This was being used to
turn on / off logging for the server
3. Similarly, remove reading the `trace` value from the initialization
options
4. Remove handling the `$/setTrace` notification
5. Remove the specialized `TraceLogWriter` used for Zed and VS Code
(https://github.com/astral-sh/ruff/pull/12564)
Regarding the (5) for the Zed editor, the reason that was implemented
was because there was no way of looking at the stderr messages in the
editor which has been changed. Now, it captures the stderr as part of
the "Server Logs".
(82492d74a8/crates/language_tools/src/lsp_log.rs (L548-L552))
### Question
Regarding (1), I think having just a simple trace level message should
be good for now as the spans are not hierarchical. This could be tackled
with #12744. The difference between the two:

**Todo**
- [x] Update documentation (I'll be adding a troubleshooting section
under "Editors" as a follow-up which is for all editors)
- [x] Check for backwards compatibility. I don't think this should break
backwards compatibility as it's mainly targeted towards improving the
debugging experience.
~**Before I go on to updating the documentation, I'd appreciate initial
review on the chosen approach.**~

2 different fixers are available in ALE :
- ruff which runs `ruff check --fix` command (useful for example when
isort is enabled in lint config),
- ruff_format which runs `run format` command.
The documentation was missing `ruff` as a possible fixer in ALE.

The documented configuration did not work. On failure, ALE suggest to
run `ALEFixSuggest`, into with it documents the working configuration
key
'ruff_format' - Fix python files with the ruff formatter.
Fix an inaccuracy in the documentation, regarding the ALE plugin for the
Vim text editor.
## Summary
Provide instructions to use Ruff together with other servers in the Kate
editor.
Because Kate does not support running multiple servers for the same
language, one needs to use the ``python-lsp-server`` (pylsp) tool.

## Summary
The purpose of this change is to explain how to use ruff as a language
server in Eglot with automatic formatting because I've struggle to use
it with Eglot. I've search it online and found that there are some
people also struggle too. (See [this reddit
post](https://www.reddit.com/r/emacs/comments/118mo6w/eglot_automatic_formatting/)
and
https://github.com/astral-sh/ruff-lsp/issues/19#issuecomment-1435138828)
## Test Plan
I've use this setting myself. And I will continue maintain this part as
long as I use it.

## Summary
This PR adds documentation for the Ruff language server.
It mainly does the following:
1. Combines various READMEs containing instructions for different editor
setup in their respective section on the online docs
2. Provide an enumerated list of server settings. Additionally, it also
provides a section for VS Code specific options.
3. Adds a "Features" section which enumerates all the current
capabilities of the native server
For (2), the settings documentation is done manually but a future
improvement (easier after `ruff-lsp` is deprecated) is to move the docs
in to Rust struct and generate the documentation from the code itself.
And, the VS Code extension specific options can be generated by diffing
against the `package.json` in `ruff-vscode` repository.
### Structure
1. Setup: This section contains the configuration for setting up the
language server for different editors
2. Features: This section contains a list of capabilities provided by
the server along with short GIF to showcase it
3. Settings: This section contains an enumerated list of settings in a
similar format to the one for the linter / formatter
4. Migrating from `ruff-lsp`
> [!NOTE]
>
> The settings page is manually written but could possibly be
auto-generated via a macro similar to `OptionsMetadata` on the
`ClientSettings` struct
resolves: #11217
## Test Plan
Generate and open the documentation locally using:
1. `python scripts/generate_mkdocs.py`
2. `mkdocs serve -f mkdocs.insiders.yml`
