ci: Remove relaxed mode from eslint (#66921)

Quick update to remove `SENTRY_ESLINT_RELAXED` from the eslint config,
and make that file look a little more similar to the getsentry version.

The GETSENTRY version of this is
https://github.com/getsentry/getsentry/pull/13274

also i took the chance to update prettier, since it runs under eslint,
to make sure that we're treating all js & ts files the same. Treating
files the same is a followup of
https://github.com/getsentry/sentry/pull/66837
