These are not specific rules, just foundational terminology definitions.
The old text was not correct, since `..b` or `..=b` single-bound patterns were stabilized in rust-lang/rust#124749 and rust-lang/rust#102275.

I was not particularly happy with how these were being presented, as I found it a bit confusing how it was combining some of the ranges, and some of the terminology it was using. I've shifted it so that it describes each of the five range kinds separately, using the same terminology from std (and the grammar). This also just has some slight wording tweaks for clarity.

This includes a series of commits which make some fixes to the range pattern rules and grammar, including a start from #1746. There were a few errors in the current description, and in general I found it a little confusing, so I reworked it a little to use consistent terminology and to describe the different range patterns individually.
