Check ruff version for compatibility with ALE

Looks like the json-lines format was added to Ruff in 2.0: https://github.com/astral-sh/ruff/commit/7b4dde0c6c95b7dfe59ef086c18539566b0df6d3

If you load vim with an updated ALE and an old ruff (e.g. `ruff==0.0.269`), instead of a version conflict message, you get this error:
```
Error detected while processing function 74_VimCloseCallback[11]..74_VimExitCallback[22]..function 74_VimCloseCallback[11]..74_VimExitCallback[15]..12[1]..69_ExitCallback[28]..68_HandleExit[24]..ale_li
nters#python#ruff#Handle:
line 4:
E491: json decode error at 'error: invalid value 'json-lines' for '--format ''
Error detected while processing function 74_VimCloseCallback:
line 11:

```

It would be nice to get something like "Minimum supported ruff version is 2.0".
