[TASK] DPL-158: Allow usage with TYPO3 v14

[sbuerk]

This change allows the usage with TYPO3 v14
and marks the starting point for developing
the support for that version.

GitHub action pipelines are also put in place
next to making Build/Scripts/runTests.sh to
allow and handle TYPO3 v14 to execute all of
the required toolchain.

Minor adjustment on unit and functional tests
are done along the way to improve the cross
TYPO3 version support, ensuring that expected
version is really executed at least for unit
and functional tests.

We need to allow minim-stability dev for now
due to the ongoing development of TYPO3 CMS.

For TYPO3 v14 excludes for TYPO3 v13 related
classes has been added to the configuration
file. All of them except one are not required
and used with TYPO3 v14. The excamption is
the InjectVariablesViewHelper requiring to
be adopted for FLUID changes and excluded
meanwhile and needs to be fixed or deprecated
in case usage is still required, which needs
to be checked.
