E999 Syntax error on match statement with python 3.10

[leddy231]

Incredible tool so far, working on replacing all of pylint in our monorepo with ruff right now, and using the vscode extension.

Bug:
Ruff seams to not be able to handle python 3.10 match cases?
Got it down to a very small working example, even specifying py310 in pyproject.toml or from command line does not work.
This example is just one python file, no pyproject.toml or ruff.toml.

Here is the small code snippet.

import os # should trigger "unused import"

match "x":
  case "x":
    print("x")

Edit:
Here is a Dockerfile that re-creates the bug, so it is nothing weird on my machine

FROM python:3.10-alpine

RUN pip install ruff
RUN echo "match 'x':"     >> test.py
RUN echo "  case 'x':"    >> test.py
RUN echo "    print('x')" >> test.py
RUN python test.py
RUN ruff --target-version "py310" test.py

All good :) We're working on it!

Fixed as of v0.0.250 which included match statement support.

@charliermarsh got this on Python 3.12.8
