Description of the changes in your PR

• Instead of using a percentage of the screen width, I now set the tag label width to 96dp. I don't know why I chose a percentage in the first place, since using a constant width works better in any layout (e.g. on tablets or TVs).
• Tags are now placed at the bottom of the description tab, with a centered TAGS label and a full visible list of tags, as requested in A better ui for tags in description #6459.

Fixes the following issue(s)

APK testing

On the website the APK can be found by going to the "Checks" tab below the title and then on "artifacts" on the right.

Please add before / after screenshots (it should be systematic when changing UI)

@B0pol You mean this should be added to the template? "Please add before/after screenshots when changing the UI of the app."

I meant systematic as in not even for newpipe but for all software contributions.
Adding it to the template is a good idea 👍
