[PATCH] SubmittingPatches: proactively monitor GHCI pages

[Junio C Hamano <gitster@pobox.com>]

Even those contributors who do not come from GGG and do not first
push their changes to their repositories on GitHub with CI enabled,
can still monitor the CI runs triggered by integration of their
topic to 'seen' and other branches to notice a breakage their topic
caused to the system.

Encourage them to help the project by keeping an eye on these CI
runs.

 Then fix the problem and push your fix to your GitHub fork. This will
 trigger a new CI build to ensure all tests pass.
