[release 1.11] Ignore some errors in typeshed (#17510)

If type-checking typeshed without errors disabled, there were some
errors in the `release-1.11` branch. These errors can break some use
cases. Ignore them for now with a quick patch. We'd probably want to
ignore them in typeshed as well before the next release after 1.11.
