This PR implements the ability to attempt to force the use of light/dark
theme in the admin panel. While I am a big advocate for the benefits
that dark mode can bring to UX, it does not always suit a clients
branding needs.
Open to discussion on whether we consider this a suitable feature for
the platform. Please feel free to add to this PR as needed.
TODO:
- [x] Implement tests (I'm open to guidance on this from the Payload
team as currently it doesn't look like it's possible to adjust the
payload config file on the fly - meaning it can't be easily placed in
the admin folder tests).
