worktree: use 'worktree' over 'working tree'
It is helpful to distinguish between a 'working tree' and a 'worktree'.
A worktree contains a working tree plus additional metadata. This
metadata includes per-worktree refs and worktree-specific config.
This is the fourth of multiple changes to git-worktree.txt, restricted
to the REFS section.
This section previously described "per working tree" refs but they are
now replaced with "per-worktree" refs, which matches the definition in
glossary-content.txt.
The first paragraph of this section was also a bit confusing, so it is
cleaned up to make it easier to understand.

-In general, all pseudo refs are per working tree and all refs starting

-exceptions, however: refs inside `refs/bisect` and `refs/worktree` are not
-shared.
