chore: fix third_party build (#9554)

The third_party folder is compiled with tsc and then rolled up in-place.
This means that the next build might try to compile the file that has
been rolled up leading to build errors. It seems the safest solution is
to always rebuild third_party folder as the size is relatively small.
