Update to Rust 1.74 and use new clippy lints table (#8722) 
Update to [Rust
1.74](https://blog.rust-lang.org/2023/11/16/Rust-1.74.0.html) and use
the new clippy lints table.

The update itself introduced a new clippy lint about superfluous hashes
in raw strings, which got removed.

I moved our lint config from `rustflags` to the newly stabilized
[workspace.lints](https://doc.rust-lang.org/stable/cargo/reference/workspaces.html#the-lints-table).
One consequence is that we have to `unsafe_code = "warn"` instead of
"forbid" because the latter now actually bans unsafe code:

```
error[E0453]: allow(unsafe_code) incompatible with previous forbid
  --> crates/ruff_source_file/src/newlines.rs:62:17
   |
62 |         #[allow(unsafe_code)]
   |                 ^^^^^^^^^^^ overruled by previous forbid
   |
   = note: `forbid` lint level was set on command line
```

README.md

flake8-to-ruff

Convert existing Flake8 configuration files (setup.cfg, tox.ini, or .flake8) for use with Ruff.

Generates a Ruff-compatible pyproject.toml section.

Installation and Usage

Installation

Available as flake8-to-ruff on PyPI:

pip install flake8-to-ruff

Usage

To run flake8-to-ruff:

flake8-to-ruff path/to/setup.cfg
flake8-to-ruff path/to/tox.ini
flake8-to-ruff path/to/.flake8

flake8-to-ruff will print the relevant pyproject.toml sections to standard output, like so:

[tool.ruff]
exclude = [
    '.svn',
    'CVS',
    '.bzr',
    '.hg',
    '.git',
    '__pycache__',
    '.tox',
    '.idea',
    '.mypy_cache',
    '.venv',
    'node_modules',
    '_state_machine.py',
    'test_fstring.py',
    'bad_coding2.py',
    'badsyntax_*.py',
]
select = [
    'A',
    'E',
    'F',
    'Q',
]
ignore = []

[tool.ruff.flake8-quotes]
inline-quotes = 'single'

[tool.ruff.pep8-naming]
ignore-names = [
    'foo',
    'bar',
]

Plugins

flake8-to-ruff will attempt to infer any activated plugins based on the settings provided in your configuration file.

For example, if your .flake8 file includes a docstring-convention property, flake8-to-ruff will enable the appropriate flake8-docstrings checks.

Alternatively, you can manually specify plugins on the command-line:

flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes

Limitations

  1. Ruff only supports a subset of the Flake configuration options. flake8-to-ruff will warn on and ignore unsupported options in the .flake8 file (or equivalent). (Similarly, Ruff has a few configuration options that don't exist in Flake8.)
  2. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule codes from unsupported plugins. (See the documentation for the complete list of supported plugins.)
