Update git submodules

* Update bifrost from branch 'master'
  to 297d2872953e43d88eaba8084125db8aa6e60c65
  - Merge "Centos: set masked: false for firewalld"
  - Centos: set masked: false for firewalld

    It appears that Centos has changed the default firewall masking state
    and as such the playbook now fails. Adding masked: false to unmask the
    unit so hopefuly bifrost works as expected.

    Also, temporarily disables the bookworm job so we can un-wedge CI
    which is broken in multiple ways including centos breakages.
