Document how to create custom navigation component for module (replacing page tree)

[tmotyl]

The flow is as follows:

1. register a new module https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/9.0/Feature-82426-NewNavigationModuleRegistrationEgPageTree.html
2. create a controller with action which will be called with ajax by the new navigation component
3. create a JS component (the one used in module registration, which will inherit from the core svgtree or PageTree

@linawolf This will also need to incorporate changes which are landing in v11 e.g. https://review.typo3.org/c/Packages/TYPO3.CMS/+/68201
