feat: add some api calls to modrinth

Calls added:
- Get version from hash
- Get versions from hashes
- Latest version of a project from a hash, loader(s), and game version(s)
- Latest versions of multiple project from hashes, loader(s), and game version(s)

Some of those are not used yet, but may be of use later on, so we have
it if we need it :)
