Merge branch 'main' into github-2923

Implement PYI006 "bad version info comparison"

## What it does

Ensures that you only `<` and `>=` for version info comparisons with
`sys.version_info` in `.pyi` files. All other comparisons such as
`<`, `<=` and `==` are banned.

## Why is this bad?

```python
>>> import sys
>>> print(sys.version_info)
sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0)
>>> print(sys.version_info > (3, 8))
True
>>> print(sys.version_info == (3, 8))
False
>>> print(sys.version_info <= (3, 8))
False
>>> print(sys.version_info in (3, 8))
False
```

+### `multiple-statements-on-one-line-def` (`E704`) was removed ([#2773](https://github.com/charliermarsh/ruff/pull/2773))
+
+This rule was introduced in v0.0.245. However, it turns out that pycodestyle and Flake8 ignore this
+rule by default, as it is not part of PEP 8. As such, we've removed it from Ruff.

+## 0.0.245
+
+### Ruff's public `check` method was removed ([#2709](https://github.com/charliermarsh/ruff/pull/2709))
+
+Previously, Ruff exposed a `check` method as a public Rust API. This method was used by few,
+if any clients, and was not well documented or supported. As such, it has been removed, with
+the intention of adding a stable public API in the future.

 ### `select`, `extend-select`, `ignore`, and `extend-ignore` have new semantics ([#2312](https://github.com/charliermarsh/ruff/pull/2312))
