Auto merge of #14620 - epage:guideless, r=weihanglo

docs: Minor re-grouping of pages

### What does this PR try to resolve?

In figuring out where MSRV documentation should live, I found the location of some items confusing
- Publishing is written in more of a guide-form, rather than reference
- Caching is written in more of a reference form, rather than a guide, and is more advanced
- Dependency references were scattered, making it harder to find

### How should we test and review this PR?
