Issue:
Missing success comments on issues
I have just noticed that `@semantic-release/github` does not comment on resolved issues. This has worked at some point in the past but seems to be broken for quite some time.

My initial suspicion is that we do not pass the correct GitHub URL to `issue-parser` at https://github.com/semantic-release/github/blob/master/lib/success.js#L56 and therefore cannot determine the correct org/repo tuple at https://github.com/semantic-release/github/blob/master/lib/success.js#L116.

Examples:

- https://github.com/semantic-release/gitlab/issues/704
- https://github.com/semantic-release/gitlab/issues/684

Pull request description:
fix: introduce dedicated option for GitHub API endpoint
Server and API endpoints can be different. Some code parts, e.g. issue parsing, need the server endpoint and we should make this explicit. The existing `githubApiPathPrefix` option is not sufficient when the API is served from a different host (like `api.github.com`).

Fixes #827
