feat(labrinth): allow protected resource and data packs to pass validation (#3792)

* fix(labrinth): return version artifact size exceeded error eagerly

Now we don't wait until the result memory buffer has grown to a size
greater than the maximum allowed, and instead we return such an error
before the buffer is grown with the current chunk, which should reduce
memory usage.

* fix(labrinth): proper supported game versions range for datapacks

* feat(labrinth): allow protected resource and data packs to pass validation
