doc: fetch: document `--jobs=0` behavior

In c39952b92 (fetch: choose a sensible default with --jobs=0 again,
2023-02-20), the `--jobs=0` behavior was (re)introduced, but it went
undocumented. Since this is the same behavior as `git -c fetch.parallel=0
fetch`, which is documented, this change creates symmetry between the two
documentation sections.

 in parallel. If multiple submodules are fetched, they will be fetched in
 parallel. To control them independently, use the config settings
