[PATCH 3/4] git-commit-graph.txt: refer to "*commit* graph file"

["Martin Ågren" <martin.agren@gmail.com>]

This document sometimes refers to the "commit graph file" as just "the
graph file". This saves a couple of words here and there at the risk of
confusion. In particular, the documentation for `git commit-graph read`
appears to suggest that there are indeed different types of graph files.

Let's just write out the full name everywhere.

The full name, by the way, is not the "commit-graph file" with a dash,
cf. the synopsis. Use the dashless form. (The next commit will fix the
remaining few instances of the "commit-graph file" in this document.)
