Follow
https://github.com/go-gitea/gitea/pull/24860#discussion_r1200589651

Use `[git.config]` for reflog cleaning up, the new options are more
flexible.

## ⚠️ BREAKING

The section `[git.reflog]` is now obsolete and its keys have been moved
to the following replacements:
- `[git.reflog].ENABLED` → `[git.config].core.logAllRefUpdates`
- `[git.reflog].EXPIRATION` → `[git.config].gc.reflogExpire`

- `PULL`: **300**: Git pull from internal repositories timeout seconds.
- `GC`: **60**: Git repository GC timeout seconds.
### Git - Reflog settings (`git.reflog`)
- `ENABLED`: **true** Set to true to enable Git to write changes to reflogs in each repo.
- `EXPIRATION`: **90** Reflog entry lifetime, in days. Entries are removed opportunistically by Git.
### Git - Config options (`git.config`)
The key/value pairs in this section will be used as git config.
