Alt Linux Apt-Rpm repository support for Forgejo packages. (#6351)

Co-authored-by: Aleksandr Gamzin alexgamz1119@gmail.com Adds support for the Apt-Rpm registry of the Alt Lunux distribution. Alt Linux uses RPM packages to store and distribute software to its users. But the logic of the Alt Linux package registry is different from the Red Hat package registry. I have added support for the Alt Linux package registry. ## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org). ### Tests - I added test coverage for Go changes... - [ ] in their respective `*_test.go` for unit tests. - [x] in the `tests/integration` directory if it involves interactions with a live Forgejo server. - I added test coverage for JavaScript changes... - [ ] in `web_src/js/*.test.js` if it can be unit tested. - [ ] in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)). ### Documentation - [x] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change. - [ ] I did not document these changes and I do not expect someone else to do it. ### Release notes - [ ] I do not want this change to show in the release notes. - [x] I want the title to show in the release notes with a link to this pull request. - [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.
