At the end of this section, we say the same but add a lot more context.

This is modeled off of `resolver.md` and is prep for moving it to other
places.

This implied SemVer's pre-1.0.0 rules,
rather than Cargo's modified SemVer policy.

The distinction between "minor" and "patch" is
[muddy](https://epage.github.io/blog/2022/02/minor-semver-issue/),
so leaving that for the more detailed documentation to cover.

This also dramatically simplifies the section.

Trying to encourage having places that "own" a concept and letting other areas
better focus.

I'm able to shrink / better focus the text as most of the content is
covered by the version field.

This will let the dependency resolution docs better focus.

This is to provide better context for the sections that come after.

We talked about three different roles of versions within the resolver in
a way that made it easy to miss some of them.
