Regression of #24536. If the user doesn't explicitly disable Actions, it
will be enabled.
1. Gitea will call `loadRepositoryFrom` before `loadActionsFrom`.
25d4f95df2/modules/setting/setting.go (L234-L237)
2. In `loadRepositoryFrom`,
`rootCfg.Section("actions").Key("ENABLED").MustBool(true)` will set
`actions.ENABLED` with `true`.
25d4f95df2/modules/setting/repository.go (L313-L315)
3. In `loadActionsFrom`, `rootCfg.Section("actions")` will get a section
with Actions enabled.
25d4f95df2/modules/setting/actions.go (L23-L26)
Although the cause of the problem was using `true` by copy-paste
mistake, it also surprised me that
**`rootCfg.Section("actions").Key("ENABLED").MustBool(true)` doesn't
only read, but also write.**
