[TEST] Change 'kind' setup in github actions so the tests run on a cluster with 2 schedulable nodes

[martin-mat]

As discussed in this PR https://github.com/cnti-testcatalog/testsuite/pull/2024

some tests are not tested properly in github actions, becuause the cluster is set up with only 1 schedulable node. Some tests require 2 schedulable nodes. Example: https://github.com/cnti-testcatalog/testsuite/actions/runs/9025631332/job/24802869636

Improve github actions and run the tests on a cluster with 2 schedulable nodes.
