McuSupport: Indicate the usage of QtCreator9+ for QtMCUs 2.3 and above

Starting from QtMCUs 2.3 legacy code is not used in McuSupport plugin
and the refactored code is used instead.
Trying to use 2.3 in older versions of QtCreator will result is using
incomplete refactored code causing errors when generating kits.

This commit will indicate to the user to choose the correct version of
QtCreator for newer QtMCUs releases.
