Bump version to 0.4.2 (#11151)

## Summary

This PR updates the playground to display the AST even if it contains a
syntax error. This could be useful for development and also to give a
quick preview of what error recovery looks like.

Note that not all recovery is correct but this allows us to iterate
quickly on what can be improved.

## Test Plan

Build the playground locally and test it.

+## 0.4.0
+
+### A new, hand-written parser
+
+Ruff's new parser is **>2x faster**, which translates to a **20-40% speedup** for all linting and formatting invocations.
+There's a lot to say about this exciting change, so check out the [blog post](https://astral.sh/blog/ruff-v0.4.0) for more details!
+
+See [#10036](https://github.com/astral-sh/ruff/pull/10036) for implementation details.
+
+### A new language server in Rust
+
+With this release, we also want to highlight our new language server. `ruff server` is a Rust-powered language
+server that comes built-in with Ruff. It can be used with any editor that supports the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) (LSP).
+It uses a multi-threaded, lock-free architecture inspired by `rust-analyzer` and it will open the door for a lot
+of exciting features. It’s also faster than our previous [Python-based language server](https://github.com/astral-sh/ruff-lsp)
+-- but you probably guessed that already.
+
+`ruff server` is only in alpha, but it has a lot of features that you can try out today:
+
+- Lints Python files automatically and shows quick-fixes when available
+- Formats Python files, with support for range formatting
+- Comes with commands for quickly performing actions: `ruff.applyAutofix`, `ruff.applyFormat`, and `ruff.applyOrganizeImports`
+- Supports `source.fixAll` and `source.organizeImports` source actions
+- Automatically reloads your project configuration when you change it
+
+To setup `ruff server` with your editor, refer to the [README.md](https://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).
+
