We are experiencing the same, with 4.25.2 and now also with 4.26.0. This started happening a couple of days ago and it is intermittent. Sometimes, after a long time, it manages to resolve the host oauth2.googleapis.com.
Small update on this one -- it seems the docker-desktop internal DNS resolver/proxy/? is not supporting DNS compression (see more on rfc1035) thus bloating the DNS response over the limit for the UDP datagram (512 bytes), which is enforced by CoreDNS.
Here are two packets, one coming from my router, the other one captured targeting the CoreDNS pod in docker-desktop. The difference is pretty clear

I came across the same issue:

It works fine on my setup with CoreDNS-1.9.4
