Documentation/notes: simplify treatment of default display refs

The main description of display refs for notes should be in
git-log.1, where there is a chance to give a leisurely description
of all the ways they can be set, what they are used for, and so
on.  The description in git-notes.1 is only meant to be a quick
reminder of how notes are used.

So simplify it.

Also add an entry for GIT_NOTES_DISPLAY_REF to the environment
section.
