Using "--dns" only modifies `/etc/resolv.conf` on first time start (instance creation) - not modified afterwards

[AndreasA]

Description

I noticed that if the initial colima instance is created with --dns 8.8.8.8 --dns 8.8.4.4 or similar those entries are written into the /etc/resolv.conf file.

However, that file does not seem to change afterwards if --dns is supplied, so colima keeps using the initially provided DNS servers - without manual changes.

checked with colima ssh -- cat /etc/resolv.conf

using vm type vz with virtiofs.

Not 100% sure if this is the intended behavior. or if the file should not change at all etc.
