Dhruv Manilawala 37ad994318 Use default settings if initialization options is empty or not provided (#11566) ... ## Summary This PR fixes the bug to avoid flattening the global-only settings for the new server. This was added in https://github.com/astral-sh/ruff/pull/11497, possibly to correctly de-serialize an empty value (`{}`). But, this lead to a bug where the configuration under the `settings` key was not being read for global-only variant. By using #[serde(default)], we ensure that the settings field in the `GlobalOnly` variant is optional and that an empty JSON object `{}` is correctly deserialized into `GlobalOnly` with a default `ClientSettings` instance. fixes: #11507 ## Test Plan Update the snapshot and existing test case. Also, verify the following settings in Neovim: 1. Nothing ```lua ruff = { cmd = { '/Users/dhruv/work/astral/ruff/target/debug/ruff', 'server', '--preview', }, } ``` 2. Empty dictionary ```lua ruff = { cmd = { '/Users/dhruv/work/astral/ruff/target/debug/ruff', 'server', '--preview', }, init_options = vim.empty_dict(), } ``` 3. Empty `settings` ```lua ruff = { cmd = { '/Users/dhruv/work/astral/ruff/target/debug/ruff', 'server', '--preview', }, init_options = { settings = vim.empty_dict(), }, } ``` 4. With some configuration: ```lua ruff = { cmd = { '/Users/dhruv/work/astral/ruff/target/debug/ruff', 'server', '--preview', }, init_options = { settings = { configuration = '/tmp/ruff-repro/pyproject.toml', }, }, } ```		2024-05-27 21:06:34 +05:30
