None of the new violations seem to be incorrect, but there are a lot of them. Moved the behaviour change behind the preview flag.

I don't know why there is a non-preview ecosystem change...

Edit: it's because the repo enables them.

rotki uses preview = true in pyproject.toml, I think there is problem in ruff_ecosystem pacakge.

possible solution is adding --force-no-preview to cli.

Thanks! Also confirmed the above (that Rotki enables preview on their develop branch).

That issues still exist on formatter, but since `black` doesn't support
`no-preview` cli arg, I didn't include it in this PR.
