fix: big file uploads (#562)

* fix: use readableWebStream() to stream asset contents

This allows the uploads to finish without mismatched Content-Length,
likely because the original method implied a wrong body encoding or
something similar. Unfortunately a GitHub server API mock was not
readily available so I had to test manually with a barebones repository.
