[PATCH v2 2/4] doc: git: link to the gitdatamodel(7) tutorial

From: Kristoffer Haugsbakk <[email protected]>

The previous commit added the first mention of gitdatamodel(7) here,
under Guides. But there are also other sections where a mention is
relevant.

Let’s mention it:

• under Description, since it is as useful as the other tutorials
  already mentioned there for those who are interested;
• under Terminology, since it complements gitglossary(7) as a
  pedagogical rather than reference source for the core terms;[1] and
• under See Also, since the other tutorials (plus the user manual) are
  mentioned there.

We don’t need to mention it under Further Documentation since we now
mention it under Description.

† 1: See dee80940 (doc: add an explanation of Git's data model,
     2025-11-12):

          `gitglossary`. This makes a good effort, but it's an
          alphabetically ordered dictionary and a dictionary is not a
          good way to learn concepts. You have to jump around too much
          and it's not possible to present the concepts in the order
          that they should be explained.

Notes (series):
    v2:
    • Msg: Correct section: s/gitdatamodel(1)/gitdatamodel(7)/[1]
    • Msg: Missing “is”[1]
    • Msg: Correct “on another page” which refers to git(1)—the same
      page that we are changing.[2] This is a mistake from my own
      iterations since this started as the first commit and I had to
      reword from: not mentioned yet; mentioned with `git help
      --guides`; (realizes that it is also automatically included in
      Guides now) ...

    v1:
    I have used double spacing for sentences since that seemed to what was
    already in use.
