test(integration): update test_resolve_dns for net-connect message split
After the --allow-net split, when no net permission is configured at all,
DNS resolution (a connect-direction op) is checked against the new
`net-connect` permission family. The resulting "NotCapable" error reads
"Requires net connect access" rather than the legacy "Requires net access",
so the no-permission assertion needs the new phrasing.
The earlier "--allow-net=deno.land" case still hits the legacy net
descriptor, so its assertion is unchanged.
