Check ruff version for compatibility with ALE

[karolinepauls]

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 <SNR>74_VimCloseCallback[11]..<SNR>74_VimExitCallback[22]..function <SNR>74_VimCloseCallback[11]..<SNR>74_VimExitCallback[15]..<lambda>12[1]..<SNR>69_ExitCallback[28]..<SNR>68_HandleExit[24]..ale_li

E491: json decode error at 'error: invalid value 'json-lines' for '--format <FORMAT>''

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