DNS resolution issues
Description
I have DNS resolution issues from my colima VM for some time now (seems to be since last upgrade).
Example : While I'm able to resolve registry-1.docker.io from the host :
Server: 192.168.6.193
Address: 192.168.6.193#53
Non-authoritative answer:
Name: registry-1.docker.io
Address: 98.85.153.80
Name: registry-1.docker.io
Address: 44.208.254.194
Name: registry-1.docker.io
Address: 3.94.224.37
I get no answer from the guest VM

;; global options: +cmd
;; Got answer:

As a result, no images can be downloaded (but it also impacts DNS generally, so impacting all containers service as soon as they need internet access)
docker container run --rm -it --name dns-test alpine sh
Unable to find image 'alpine:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 127.0.0.53:53: no such host.
See 'docker run --help'.
In the meantime, some other FQDNs work from the guest VM : ......
