Subject: [PATCH] fix: tolerate null bugs URLs (#6798)

Currently, if the bugs URL returned from `package.json`, which is
processed through
[hosted-git-info](https://github.com/npm/hosted-git-info), is falsy, an
error is thrown. However, hosted-git-info may well return a falsy bugs
URL. This can happen when there is no bugs URL in the repo, but
hosted-git-info tries to infer one, but one cannot be inferred, for
example if the repository URL is a SourceHut URL. This is described
here: https://github.com/npm/hosted-git-info/pull/213

For this reason, we should tolerate falsy URLs and fall back to whatever
is defined in `bugs.js`, in this case being sent to
https://www.npmjs.com/package/<packageName>.
