Upgrade to AdminLTE 3

[core23]

Subject

This is a new approach to solve #7156. It is basically based on #7740.

I am targeting this branch, because the style update is a breaking change. Some css classes changed when upgrading from bootstrap 3 > 4 (e.g. box became card).

Closes #7156

- Add support for jQuery v3

I think your description is wrong, should be from bootstrap 3 > 4?

from bootstrap 3 > 5

AdminLTE 3 is using Bootstrap 4
AdminLTE 4 (WIP, not released yet) is using Bootstrap 5

You're right. There's plenty to do to use bootstrap 5: https://github.com/ColorlibHQ/AdminLTE/milestone/7

Paused until #8117 is solved
