Description of problem:
The forge macros do not currently support git.sr.ht. Can you please consider implementing support? I would submit a PR, but unfortunately, I'm not competent enough in lua.

Version-Release number of selected component (if applicable):
redhat-rpm-config-199-1.fc35.noarch

How reproducible:

See https://src.fedoraproject.org/fork/gotmax23/rpms/aerc/blob/rawhide/f/aerc.spec for an example. The go macros depend to the forge macros, so in order to use a source archive from git.sr.ht, it is necessary to define 8 extra macros.

```

# https://git.sr.ht/~rjarry/aerc
%global goipath         git.sr.ht/~rjarry/aerc
%global forgeurl        https://git.sr.ht/~rjarry/aerc
Version:                0.6.0
%global tag             %{version}
%global repo            aerc
%global archivename     %{repo}-%{tag}
%global archiveext      tar.gz
%global archiveurl      %{forgeurl}/archive/%{tag}.%{archiveext}
%global topdir          %{archivename}
%global extractdir      %{archivename}
%global scm             git

%forgemeta
```

As you can see, the archiveurls are generated using `%{forgeurl}/archive/REF.%{archiveext}`. `REF` can be a commit, tag, or a branch.

Thanks,
Maxwell
