Add the /help page in robots.txt
What does this MR do?
Exclude the /help
page from being crawled. This change is two-fold:
- Do not let search engines index the help page of every GitLab installation out there. Searching for
gitlab help
now yields many results from the help page of random instances. - The
/help
page mostly has links to internal docs, and we prefer to link to the external docs website instead.
