Docs: Add note on size check time interval
Problem to solve
GitLab (particularly Support) often gets questions/complaints that the size of their project is not accurately reflected.
Further details
As per the project cache worker, the size is updated at most every 15 minutes.
Project size is displayed on the project admin page, but most users would see it on the project page. Example: GitLab CE
We may also need an engineer to let us know (based on the code) if the interval applies to any of the other stats on the project page or just the size.
Proposal
Not sure where to document this as we do not have an existing docs page.
I can't find user docs that mention project size (aside from GL.com limit). On the admin side, we have the repo size limit page
We have a note on the overall size for GitLab.com in two places:
- https://docs.gitlab.com/ee/user/project/repository/#repository-size
- https://docs.gitlab.com/ee/user/gitlab_com/#repository-size-limit
but this polling internal is not specific to .com
