## Summary This PR introduces two new AST nodes to improve the representation of `PatternMatchClass`. As a reminder, `PatternMatchClass` looks like this: ```python case Point2D(0, 0, x=1, y=2): ... ``` Historically, this was represented as a vector of patterns (for the `0, 0` portion) and parallel vectors of keyword names (for `x` and `y`) and values (for `1` and `2`). This introduces a bunch of challenges for the formatter, but importantly, it's also really different from how we represent similar nodes, like arguments (`func(0, 0, x=1, y=2)`) or parameters (`def func(x, y)`). So, firstly, we now use a single node (`PatternArguments`) for the entire parenthesized region, making it much more consistent with our other nodes. So, above, `PatternArguments` would be `(0, 0, x=1, y=2)`. Secondly, we now have a `PatternKeyword` node for `x=1` and `y=2`. This is much more similar to the how `Keyword` is represented within `Arguments` for call expressions. Closes https://github.com/astral-sh/ruff/issues/6866.
