What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)
Branch for upgrade from bootstrap 4 to bootstrap 5.

Official link for Bootstrap migration:
https://getbootstrap.com/docs/5.0/migration/

Generally tried to recreate behavior and look as it was in v4.

What still needs to be addressed:

The hack for bootstrap accordions, that we use in v4, is not yet removed in v5.

Thorough testing probably required again (last time was before a lot of fixes).

What has been changed:

Some of the details of the changes (taken from my local documentation):

• reintroduced the href underlines since they are not underlined in bootstrap 5 by default
• helpdesks migrated
• lots of renaming things:
  • form-checkbox -> form-check
  • custom-control-input -> form-check-input
  • badge badge-light -> badge badge-light text-dark
  • “custom-control custom-radio custom-control-inline” -> “form-check form-check-inline”
  • data-toggle=”pill” -> data-bs-toggle=”pill”
  • .pl-* and .pr-* -> .ps-* and .pe-*.
  • .border-left and .border-right -> .border-start and .border-end.
  • .text-left and .text-right -> .text-start and .text-end.
• Navbars now require a container within (to drastically simplify spacing requirements and CSS required).
• fixed accordions (for profile/subscriptions, lecture/form and start page)
• Remove form-group, replace with form-floating mb-3
• Jumbotron removed, has to be replaced with other utilities

Fixed issues as are outlined in basecamp: https://3.basecamp.com/3978947/buckets/7198402/todos/5678353440#__recording_5887260341

and more changes as are outlined in the official link for migrating v4 to v5.

To migrate an accordion:
change “card” to “accordion-item”
change “div class=”card-header clickable”” zu “button class=”accordion-button collapsed””
change “data-” to “data-bs-”
change “card-body” to “accordion-body”
