[red-knot] Add basic on-hover to playground and LSP (#17057) 
## Summary

Implement a very basic hover in the playground and LSP.

It's basic, because it only shows the type on-hover. Most other LSPs
also show:

* The signature of the symbol beneath the cursor. E.g. `class
Test(a:int, b:int)` (we want something like
54f7da25f9/packages/pyright-internal/src/analyzer/typeEvaluator.ts (L21929-L22129))
* The symbols' documentation
* Do more fancy markdown rendering

I decided to defer these features for now because it requires new
semantic APIs (similar to *goto definition*), and investing in fancy
rendering only makes sense once we have the relevant data.

Closes [#16826](https://github.com/astral-sh/ruff/issues/16826)

Ruff Python Parser

Ruff's Python parser is a hand-written recursive descent parser which can parse Python source code into an Abstract Syntax Tree (AST). It also utilizes the Pratt parsing technique to parse expressions with different precedence.

Try out the parser in the playground.

Python version support

The parser supports the latest Python syntax, which is currently Python 3.12. It does not throw syntax errors if it encounters a syntax feature that is not supported by the target-version. This will be fixed in a future release (see https://github.com/astral-sh/ruff/issues/6591).
