Add documentation for how to upgrade when using NX

[fpaaske]

It would be great if you could add documentation on how to perform an upgrade of NX, NativeScript/nx, NativeScript, and the different "view" frameworks (Angular, Vue, ..).

So if I'm on NX 15, NativeScript/nx 15, NativeScript 8.6, Angular 16 or some other combination; what's the best upgrade path to get the latest versions that fits together.

What is the process to update?

Thanks in advance!
