TASK: Introduce ContentRepository::getNodeType to simplify 80% use

[mhsdesign]

$contentRepository->getNodeTypeManager()->getNodeType() will be aliased as $contentRepository->getNodeType() to make the 90% usecase easy ... basically the same we are doing for getContentSubgraph() and findWorkspaceByName()

that way we probably dont need a higher level utility as fetching the cr would be just enough see #5065

Yes nice idea, but I would say passing through methods from dependencies is very bad API design, I am opposed to this change.

thanks for the quick feedback, i did it just to have something concrete to discuss, as we often came to the need of some higher level api to make things simpler and instead i thought why not make the low level thing more fun :D

(#5065)

but we can easily discuss that also for Neos 9.1 or later :)
