CentOS installation instructions are missing from https://about.gitlab.com/install/#centos-7
On this page https://docs.gitlab.com/ee/administration/package_information/supported_os.html there is a link "Use CentOS installation documentation" which goes to https://about.gitlab.com/install/#centos-7
This documentation has the same link: https://gitlab.com/gitlab-org/gitlab/-/blob/master/doc/administration/package_information/supported_os.md
https://about.gitlab.com/install/#centos-7 is missing the installation instructions for CentOS though.
