The guide "gitsubmodules" was added in d480345 (submodules: overhaul
documentation, 2017-06-22), but it was not added to
command-list.txt when commit 1b81d8c (help: use command-list.txt
for the source of guides, 2018-05-20) taught "git help" to obtain the
guide list from this file.

Add it now, and capitalize the first word of the description of
gitsubmodules, as was done in 1b81d8c (help: use command-list.txt
for the source of guides, 2018-05-20) for the other guides.
