Create doctor command to fix repo_units broken by dumps from 1.14.3-1.14.6 (#17136) (#17137)

Browse Source 
Backport #17136

There was a serious issue with the `gitea dump` command in 1.14.3-1.14.6 which led to corruption of the `config` field of the `repo_unit` table. 

This PR adds a doctor command to attempt to fix the broken repo_units. Users affected by #16961 should run:

```
gitea doctor --fix --run fix-broken-repo-units
```

Fix #16961
