This allows `nix flake metadata` and nix in general to lock a *branch*
tarball link in a manner that causes it to fetch the correct commit even
if the branch is updated with a newer version.
For further context, Nix flakes are a feature that, among other things,
allows for "inputs" that are "github:someuser/somerepo",
"https://some-tarball-service/some-tarball.tar.gz",
"sourcehut:~meow/nya" or similar. This feature allows our users to fetch
tarballs of git-based inputs to their builds rather than using git to
fetch them, saving significant download time.
There is presently no gitea or forgejo specific fetcher in Nix, and we
don't particularly wish to have one. Ideally (as a developer on a Nix
implementation myself) we could just use the generic tarball fetcher and
not add specific forgejo support, but to do so, we need additional
metadata to know which commit a given *branch* tarball represents, which
is the purpose of the Link header added here.
The result of this patch is that a Nix user can specify `inputs.something.url =
"https://forgejo-host/some/project/archive/main.tar.gz"` in flake.nix
and get a link to some concrete tarball for the actual commit in the
lock file, then when they run `nix flake update` in the future, they
will get the latest commit in that branch.
Example of it working locally:
» nix flake metadata --refresh 'http://localhost:3000/api/v1/repos/jade/cats/archive/main.tar.gz?dir=configs/nix'
Resolved URL: http://localhost:3000/api/v1/repos/jade/cats/archive/main.tar.gz?dir=configs/nix

In `repo.RemoveDependency`, use `PostFormValue` instead of
`PostForm.Get`. The latter requires `ParseForm()` to be called prior,
and in this case, has no benefit over `PostFormValue` anyway (which
calls `ParseForm()` if necessary).
While this currently does not cause any issue as far as I can tell, it
feels like a bug lying in wait for the perfect opportunity. Lets squash
it before it can do harm.

Adjust the `anyHashPattern` to match URL query parameters too, and
adjust `fullHashPatternProcessor` accordingly.
Includes a test case, and an update to an existing one to account for
the new capture group.
Fixes#3548.

Also add a test for GogsDownloaderFactory.New() to make sure
that the URL of the source repository is parsed correctly.
When the source gogs instance is hosted at a subpath like `https://git.example.com/gogs/<username>/<reponame>` the migration fails.
This PR fixes that.

To be able to easily test cases where the repository does not have any
code, where the git repo itself is completely uninitialized, lets
support a case where the `AutoInit` property is false.
For the sake of backwards compatibility, if the option is not set either
way, it will default to `true`.
