CI: migrate to respdiff v2

All resolvers are configured as recursors (no forwarding).
We should extend testing so we can test recursion and forwarding at the
same time.

List of queries is taken dynamically from
https://gitlab.labs.nic.cz/knot/knot-resolver/snippets/69
This will likely change in future.

The test will fail if mismatch rate >= 1 %.
This is error margin for network instability and few possibly broken upstreams
in the test list.
