Allow force push to protected branches (#28086) Fixes #22722 ### Problem Currently, it is not possible to force push to a branch with branch protection rules in place. There are often times where this is necessary (CI workflows/administrative tasks etc). The current workaround is to rename/remove the branch protection, perform the force push, and then reinstate the protections. ### Solution Provide an additional section in the branch protection rules to allow users to specify which users with push access can also force push to the branch. The default value of the rule will be set to `Disabled`, and the UI is intuitive and very similar to the `Push` section. It is worth noting in this implementation that allowing force push does not override regular push access, and both will need to be enabled for a user to force push. This applies to manual force push to a remote, and also in Gitea UI updating a PR by rebase (which requires force push) This modifies the `BranchProtection` API structs to add: - `enable_force_push bool` - `enable_force_push_whitelist bool` - `force_push_whitelist_usernames string[]` - `force_push_whitelist_teams string[]` - `force_push_whitelist_deploy_keys bool` ### Updated Branch Protection UI: <img width="943" alt="image" src="https://github.com/go-gitea/gitea/assets/79623665/7491899c-d816-45d5-be84-8512abd156bf"> ### Pull Request `Update branch by Rebase` option enabled with source branch `test` being a protected branch: ![image](https://github.com/go-gitea/gitea/assets/79623665/e018e6e9-b7b2-4bd3-808e-4947d7da35cc) <img width="1038" alt="image" src="https://github.com/go-gitea/gitea/assets/79623665/57ead13e-9006-459f-b83c-7079e6f4c654"> --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
