Description

When auto gc occurs, the actual repo size is shrinked, but the repo size on web interface isn't updated accordingly.

For example, today I pushed recent commits on git.git (Git SCM repo) to my local Gitea instance, then auto gc was invoked.
After auto gc, the repo size was about 132 MiB, but on the web interface the size was still 211 MiB (before gc)

Screenshots

on web interface, repo size: 211 MiB

git count-objects -v when accessing the interface, repo size: 132 MiB

UpdateSize is only called during PushUpdates - I guess the auto gc happened after PushUpdates was called.

I'm not really sure what we can do - updating size is an expensive function. The only thing I can imagine is a cron task that can be called to update things.

add it to the cron task that gc repos?

@6543 seems ok
