These paths were added in the 13.3.3 security release [1] so they would
get throttled by the "protected paths" rate limit, as a protection
against brute-force attacks.

This rate limit turned out to be to strict for normal OAuth usage [2],
so we're removing the paths again and instead let them get throttled by
the general rate limit for unauthenticated requests, which didn't exist
yet when we made the original change, and should still offer sufficient
protection.

This configuration change was already applied manually on gitlab.com
and verified to be working as expected. [3]
