fix: LFS GC is never running because of a bug in the parsing of the INI file (#9202)

After https://github.com/go-gitea/gitea/pull/22385 introduced LFS GC, it never worked due to a bug in the INI library: fields in structs embedded more than one level deep are not populated from the INI file.

This PR fixes the issue by replacing the multi-level embedded struct with a single-level struct for parsing the cron.gc_lfs configuration.

Added a new test for retrieving cron settings to demonstrate the bug in the INI package.

---

Fix #9048 by cherrypicking the fix from Gitea

Gitea PR: https://github.com/go-gitea/gitea/pull/35198

Confirmed to work on my own instance, I now see the cron schedule for gc_lfs listed in the site admin menu where it was empty before
