c8s integration jobs are broken because of failure during installing r10k

[Takashi Kajinami]

Currently c8s integration jobs in <=stable/yoga are consistently failing.
Looking at the job log it seems installing r10k fails because it tries to pull puppet_semantics which is not compatible with old ruby version c8s.

    Stable-only: Pin semantic_puppet in CentOS 8

    semantic_puppet >= 1.1.0 requires ruby >= 2.7.0 so can no longer be
    installed in ruby 2.6.0 in CentOS 8.

    Backport note:
    This backport removes the version check, because we run no tests in
    CentOS 9 in this branch while we run some tests in CentOS 7.
    In addition, distro check is also removed, because the same pin is
    required in Ubuntu Bionic.

    Also, pinning of puppet_forge is removed, because r10k 2.6.4 requires
    puppet_forge 2.2.8, which is conflicting with the pin which requires
    2.2.6 .

    Conflicts:
            install_modules.sh
