import: github: Gracefully handle projects that have disappeared.
Fixes <https://bugs.gnu.org/42509>.
Reported by Alexandru-Sergiu Marton <brown121407@posteo.ro>.
* guix/import/github.scm (fetch-releases-or-tags): Use 'http-fetch'
instead of 'json-fetch', and guard against 404 errors. Upon 404, emit a
warning and return the empty vector.
