use `mtt` action for integration tests

[BuckarooBanzay]

This PR removes the manual integration-testing files and switches to the mtt action.

It currently tests against latest engine release 5.8.0 and current master/main branches of the dependencies (game and mods)

Note: The test against 5.5.0 is removed now due to some gh-action limitations (https://github.com/BuckarooBanzay/mtt/issues/4) IMO: we should let go of the old engine versions anyway

[BuckarooBanzay]

I'd be happier if test specific stuff would be in some sub dirs dedicated for tests, I mean similar how it was.

There's only the mtt.lua and registered_nodes.txt in the "main" technic mod-folder, i could move them to a "test" directory if you want...

[OgelGames]

I think it would be good to keep the .test directory for those files, even though it's only two; it keeps the mod directories cleaner, and they automatically get excluded from releases.

Actually now that I look at it closer, those are only tests for technic, so it would make more sense to keep them in there.
