[doc_checker] Refactor link verification to be more robust.

We used to run into error code 429 (too many requests) on a few servers.
Note that this makes the tool significantly slower (~2 minutes). There are ways this can be sped up in the future.

Test: manually ran the tool and verified that it completed.
