Fix usability problems for file template

This commmit is the start for issue 30807 and
resolving usability problems with file templates.
I've moved the exisiting UI and changed some functionality.

Use toast component to undo template actions

Set active class to template type

Fix failing rspec tests

Fixed failing rspec tests due to refactor
of the UI. New functionality was introduced
so the tests needed to be reworked.

Fix failing test and add mobile styles

Generate changelog for merge request

Fix eslint errors for i18n

Fix failed job due to locale/gitlab.pot

Fix linting error in haml file

Change dropdown labels and fix dropdown headers

Adjust rspec for template selectors

Change toggle text after undo template action

Fix broken toast due to udpated master

Remove toggle label on template selector

Fix failing rspec tests due to toggle text change

Remove un-need conditional check

Add template selection to toast

Adjust rspec to pass for undo action
