Comment:

 Has duplicate #56065.

 In the same direction, #56065 asks for an option to change the default
 regex for tags without exposing deep many details of the github port
 group. Seems like both could be solved with a set of new options:

 * `github.livecheck.page [releases|tags]`\\
   Not using `.url` as it is not supposed to be a full URL, but relative to
 the homepage at github. Defaults to `tags` for backwards compatibility.\\
   Implemented with `default livecheck.url
 ${github.homepage}/${github.livecheck.page}`.
 * `github.livecheck.tag_regex ...`\\
   The regex to be matched against the tag name. Defaults to `[join
 ${github.tag_prefix} ""](\[^"\]+)`.\\
   Implemented with `default livecheck.regex
 archive/${github.livecheck.tag_regex}${extract.suffix}`.

 Does this seem reasonable?
