[PATCH 6/6] doc: fix grammar errors in submodule description

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

6cc6d1b4c699 (Documentation: update add --force option + ignore=all
config, 2026-02-06) added text describing both the ignore=none and
ignore=all behaviors.  The former had minor formatting and grammatical
errors, while the latter was a bit garbled.  I have tried to tweak the
wording on the latter to make it read as I think was intended, and fixed
the minor grammatical issues with both as well.
