Add 2 empty lines between v2 quirk definitions

[TheJulianJES]

Proposed change

This adds two empty lines between each v2 quirk definition when there are multiple in a single file.

Additional information

This was done inconsistently before and pre-commit/ruff doesn't enforce this, since we don't create a new class here or anything. So, this PR just adds them manually to existing files.

Checklist

• The changes are tested and work correctly
• pre-commit checks pass / the code has been formatted using Black
• Tests have been added to verify that the new code works
