D10 support for the 8.x-1.x branch

I made some changes and the 8.x-1.x branch seems to be working fine on D10.4, I'll leave it for "Needs Review" for a while, then I'll merge it to the 8.x-1.x branch. Screenshot attached.

I'll merge it to the 8.x-1.x branch so anyone can test it by installing the Development version: https://www.drupal.org/project/fluidui/releases/8.x-1.x-dev →

Please let us know if you run into issues, we'll plan to release a tagged release soon.
