ci: rollout several recent changes to CI testing

[richm]

• Pass in a YAML true value as __bootc_validation: true using
  the --extra-vars option to ensure that __bootc_validation is
  treated as a boolean and not a string value.

-e "__bootc_validation: true"

You can also use JSON format:

-e '{"__bootc_validation": true}'

but YAML is simpler in this case.

• Use tox-lsr version 3.11.1

• Ensure the citest bad comment works when the test was cancelled in
  addition to the failure case.

• Update contributing.md documentation

• Update number of nodes to use in testing farm, if needed

• remove unnecessary ansible-lint skips
