Add setup docs for Zed editor

[dhruvmanila]

Summary

This PR adds the setup documentation for using Ruff with the Zed editor.

Closes: #12388

[samueller]

I've read the setup docs, but still can't figure out how to add linting options. For example, where in Zed's settings.json do I add the option for quote-style? The docs give examples for pyproject.toml and ruff.toml and I've tried many possible places in settings.json, but can't figure it out.

@samueller sorry that you're struggling with this.

The editor doesn't support all ruff settings. It only supports a subset and quote-style isn't part of that subset. To configure the quote-style, you have to create a pyproject.toml or ruff.toml and set the quote style in there.

It only supports a subset and quote-style isn't part of that subset.

I understand, thank you for letting me know

@samueller Sorry that you struggled with this. Do you have any recommendation on how can we improve this in the documentation to make it clearer?

Would have been great to have read which subset of features work in Zed's settings.json and which don't in the Zed configuration section.

I'm curious to know whether the following section in https://docs.astral.sh/ruff/editors/setup/#zed conveys this:

To configure the language server, you can provide the server settings under the lsp.ruff.initialization_options.settings key:

{
  "lsp": {
    "ruff": {
      "initialization_options": {
        "settings": {
          // Ruff server settings goes here
          "lineLength": 80,
          "lint": {
            "extendSelect": ["I"],
          }
        }
      }
    }
  }
}

I had seen that, but it didn't tell me the settings that won't work, such as quote-reply. I had assumed all settings would work, I just needed to figure out how to specify them in settings.json.

I see, thanks for the insight. I think it makes sense to explicitly clarify this point in the docs.
