fibers release bits [was: Re: Moving Fibers to Codeberg]

Back in July Fibers moved to Codeberg (yay!).

I'm looking at updating the pkgsrc package, currently at 1.3.1.

The README on codeberg points to

  https://codeberg.org/guile/fibers/releases

for download, and I don't see links for tarballs.  I see some NEWS type
content, and a tag with a git hash.

I have no idea if the tarball is just a tarred up repo, or if it's
automake-style 'make dist'.  I can certainly clone and see the bits, but
I'm confused by the lack of a wget'able tarball that I could
configure/make/make-install in a git-clueless sort of way.

Any clues appreciated.
