bug#42509: guix refresh: Error downloading release information through the GitHub API

[Alexandru-Sergiu Marton]

Hi,

I tried running `guix refresh` and it gave me this error (after
correctly reporting around 100 packages to be updated):

--8<---------------cut here---------------start------------->8---

I have the GUIX_GITHUB_TOKEN environment variable set.

I'm on commit e4d341fa74d005cc3cd1437a1908ba1993d54d5b.

Cheers,
