chore: Bump GATOR_VERSION to 1.17.0 from 1.16.3

In the 1.17.0 version of gator (which I've been using on my machine),
the `--experimental-enable-k8s-native-validation` flag has been renamed
to `--enable-k8s-native-validation`.  This was preventing me from using
the `make verify-gator` target.

This PR fixes updates the GATOR_VERSION and changes the flag.
