sort list of active plugins in config file

Check-list

• [ ] There is a linked issue discussing the motivations for this feature or bugfix
• [ ] Unit tests have been added where possible
• [ ] I've added / updated documentation for any user-facing features.
• [ ] Performance seems to be comparable or better than current main

What this change is adding / fixing

I store the config in version control (git) and without sorting the list of active plugins it may look changing for version control without any changes
