Due to https://github.com/inspec/inspec/issues/7029, omnibus-gitlab
will not work if parser 3.3.1.0 and up are installed. Patch the gem
with https://github.com/inspec/inspec/pull/7030 until an update is
available. This will avoid failures if parser 3.3.1.0 is installed and
prevent incidents such as
https://gitlab.com/gitlab-com/gl-infra/production/-/issues/17954.

Changelog: fixed
