In order to do that, you want this:

in /etc/nsswitch.conf:
...
hosts:          files dns
...

Which is the standard for Debian and basically all other Linux
distros that I know about.

That tells the DNS resolver to look at /etc/hosts first, and
then make a DNS query if /etc/hosts does not have an answer.

Note that isn't in resolv.conf, it's in nsswitch.conf.
