It's not immediately clear for new users that editing the
"File Browser" colors will also adjust the "Asset Browser".
Similar to how it's already the case for UV/Image Editor,
mention in the name of the panel other editors that share
the same color settings.
* Dope Sheet > Dope Sheet/Timeline
* File Browser > File/Asset Browser
* Graph Editor > Graph Editor/Drivers
The only exception is Node Editor because eventually it
will get too long.
