Tag fetching

[Alystrasz]

When the verify_versions.py script fetches tags of a mod repository, it only accesses the first tag page (e.g. https://api.github.com/repos/{}/{}/tags), while tags resource is paginated (i.e. searched tag might not be on the first results page).

See #16 (comment) for pages example.

From what I can gather, there is indeed no way to reorder or increase the number of tags fetched. One possible alternative is to instead pull the tag from the latest release, e.g. https://api.github.com/repos/{}/{}/releases/latest. The field seems to be tag_name.

Problem with the latest endpoint is that it would stop developers from working on their mods as long as the mod validation process is not over.
