Improve contributors licenses screens

[flofriday]

Description

Closes #7123
Closes #7124

This PR includes the following Changes:

• Adds rounded corners to the avatars of the contributors pages
• Removes empty space on the License and Translator pages
• Makes Contributors clickable wich opens their GitHub profile in a browser
• Makes Licenses clickable which opens the corresponding project
• All clickable items have a ripple effect to indicate their "clickability ???"

I combined both issues as they work on improving the same parts of the codebase and since both aren't too large on their own.

Screenshots

On some screenshots I tried to capture the ripple effect, which didn't work too well but you get the gist.

I think think this is still a work in progress as I just discovered that the licenses already had a well designed menu that pops up when clicked on, which my solution no longer produces.

I reimplemented the clicking on developers and special thanks members, which is now much closer to how the licenses screen does it and fit's in better with the existing code.
Also now the licenses display their popup again which already worked great.

Functionally nothing else changed so it still looks like in the screenshots above, with ripples and all.
