[5.4] Add compat6 behaviour plugin to 5.4 with enabled options

Pull Request for Issue # .

Follow up to PR #45371 .

Summary of Changes

With pull request (PR) #45371 the backwards compatibility (b/c) plugin for Joomla 6 from PR #45336 has been added to the 5.4-dev branch so that the plugin is already available and active on Joomla 5.4 when we update to Joomla 6.

This PR here completes that by making sure that the plugins' options are enabled on update to Joomla 6 so we can be sure a 3rd party system or behaviour plugin which will require these options on Joomla 6 does not cause the update to fail.

As the update SQL scripts modified by this PR have not been released yet we safely can change them.

Testing Instructions

Code review is sufficient.

Check that the params values changed by this PR here fits to the corresponding values in PR #45480 .
