[alanmcanonical]

Description:

• Remove xserver-common instead of xserver-xorg

Rationale:

• CIS jammy v2 requires xserver-common to be removed.
• STIG ubuntu doesn't use this rule.

Hi @alanmcanonical. Thanks for your PR.

I'm waiting for a ComplianceAsCode member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

lgtm, thanks!
the CI failures for SLEs, Debian and so on is unrelated to this change.
