Improvementgood first issue
Description
Issue details
When adding new site credentials, you have to manually enter the domain in the ~/site-credentials/new page. Wallabag doesn't give any clue on the supported ones.
A solution could be to have a scrollable list of supported domains or a documentation page referencing them for the user, with a way to request the addition of another.
Thanks!
Environment
Wallabag.it version 2.3
Steps to reproduce/test case
Add new site credentials for a paywall.
