Add refs from other pages where it might come up.
I also added a bit of detail and rephrased to address some Vale linter
warnings.

This mostly edits the get started with MRs guide to use the same tone
and patterns as the get started with compositions guide.

The goal of this guide is to:
* Introduce composition as a standalone concept (i.e. no MRs needed)
* Showcase a namespaced composition
* Showcase some different composition functions - i.e. different config language options
I'm also taking a different approach to the previous getting started guides, in that
I'm leaving out a lot of explanation of what things are. Instead I'm prioritizing having
folks apply things (even if they don't fully understand them) and seeing the results.
I feel more detailed explanations should come after the get started guides - e.g. in the
concepts section.
