Remove the `ruff` to `ruff check` alias

[MichaReiser]

We deprecated the ruff to ruff check, ruff --explain to ruff rule, ruff --generate-shell-completion to ruff generate-shell-completion and the ruff --clean to ruff clean aliases in 0.3. Ruff 0.5 changed the commands to error. We should remove the aliases in an upcoming minor release.

#10169
#12011

Note that the ruff-lsp used the ruff to ruff check alias astral-sh/ruff-lsp#392

[MichaReiser]

#12011 made using any of the above commands a hard error, but we keep printing an error. We should remove the commands entirely in a future release (0.6? or 0.7?)

So the current state is that these have a custom error, and the task here is to remove the custom errors?
