Installing GitLab on Raspberry Pi 64-bit OS

What this post added

This post details a manual workaround for installing GitLab CE on Raspberry Pi OS 64-bit by manually configuring apt sources to use Debian Buster repositories, as official ARM64 support was still in development at the time of writing. It outlines the steps to fetch the script, update apt, install prerequisites, create a new sources list file, and add the necessary repository entries before performing the standard installation.
