feat: Replace Press Alt+K to show keyboard shortcuts warning

[BrayanDSO]

Fixes

• Fixes Remove/Replace Press Alt+K to show keyboard shortcuts warning #17633

Approach

In the commits. The shortctus helper can be improved later based on David's comment:

Display a help item in the controls settings if a keyboard is attached
Which opens up the keyboard and educates users on the keyboard shortcut for 'Keyboard Shortcuts'
(extension/to discuss) Potentially make it a dismissable banner? It's probably only useful a few times, and then ends up taking up space

How Has This Been Tested?

Android 14 tablet:

The keyboard is being added/removed to check if the helper only appears with a physical keyboard attached.
