Bug 1823694 - [lint.ruff] Disable some warnings we don't actually want to enforce, r=linter-reviewers,andi

This disables:
PLR0911     too-many-return-statements
PLR0912     too-many-branches
PLR0913     too-many-arguments
PLR0914     too-many-return-statements
PLR2004     magic-value-comparison

This removes nearly 2000 warnings.
