Hi Guix,

I'd like to merge go-team to master branch after a good amount of
updates and missing packages were placed.

- 27 packages added
- 47 packages updated
- 21 packages have tests enabled

The changes make it easy to add Prometheus patches from 
- Prometheus (and Alertmanager) <https://issues.guix.gnu.org/40738>
- [PATCH 00/47] gnu: Add go-github-com-prometheus-prometheus. <https://issues.guix.gnu.org/54560>

Thanks,
Oleg
