Skip failing IPv6 tests in CI

These tests have been failing on the `test` pipeline CI for a while, but they run fine locally on the systems that support ipv4 and ipv6

since we have `test-ipv6` pipeline that runs full test suite in a docker image with IPv6 enabled,
we should be okay to skip these Tests on the `test` pipeline.

The reason these tests are failing is because they are using `net.Listen("tcp", "localhost:0")`,
the use of `tcp` network expects both IPv4 and IPv6.
