[bug#62156] [PATCH v4 2/2] lint: Append "/info/refs" to git-reference-url.

[Felix Lechner]

For the atftp package added in the preceeding commit, lint produced this
warning:

  gnu/packages/networking.scm:2924:5: atftp@0.8.0:
    URI https://git.code.sf.net/p/atftp/code not reachable:
      404 ("Not Found")

Thanks to Sergey Trofimov for suggesting a fix! [1]

It was implemented here, and the warning disappeared.

* guix/lint.scm (check-source): Append "/info/refs" to git-reference-url.
