Summary of Changes

Currently, if version history is enabled for a component, every view extends FormView class from that component will have Versions button shown, even if that view does not really support versions history. This PR just fixes that wrong behavior. The button will only be shown if:

• Versions History is enabled for the component
• The model associated with the view implements VersionableModelInterface (the modern version history implement supported from 6.0)
• Or the associated table implements VersionableModelInterface

Testing Instructions

• Enable Versions History for com_content. Then edit an article and make sure Versions button is still being displayed
• Disable Versions History for com_conent. Then edit an article and make sure Versions button is not being displayed

Basically, make sure versions history still work with this PR applied. Then we will wait for @Ruud68 test confirms that it works well for his custom extension

Actual result BEFORE applying this Pull Request

Versions button is always shown for every views extends FormView class even if that view does not support versions history

Expected result AFTER applying this Pull Request

Versions button is only shown for views extends FormView class if that view support versions history
