Re-enable OpenCollective and Realmeye

- Updated OpenCollective to use status_code detection (previously used message detection)
- Added Realmeye with message detection

Both sites were previously removed due to false positives but have been verified to work correctly now:
- OpenCollective: Returns 200 for existing profiles, 404 for non-existent
- Realmeye: Shows 'Sorry, but we either:' error message for non-existent players

Tested with known usernames:
- OpenCollective: sindresorhus
- Realmeye: rotmg

Note: PowerShell Gallery was initially included but removed after discovering their /profiles/ endpoint no longer works.
