Update comps-groups scenarios for dnf5

[glum23]

Several scenarios have been updated for dnf5. There are still scenarios waiting for clarification and resolution of related issues (comments have been provided).

Hello @glum23, Scenario: 'dnf group list -C' works for unprivileged user even when decompressed could be also enabled for dnf5 as it is after merging the rpm-software-management/dnf5#786. So maybe, if can I ask you please, you could enable it in your PR and I can rerun the CI then after the given PR is merged.

@jan-kolarik, the scenario has been enabled.

I am sorry but this change cannot be merged because the feature from rpm-software-management/dnf5#786 will be implemented alternatively.

I dropped this single test related to cacheonly functionality and added a comment with a reference to related issue.
