Jade Lovelace 900381d6e9 Add an immutable tarball link to archive download headers for Nix
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
