Add ability to repoint the repo for scripts

🌟 Briefly describe the feature

Add ability to repoint the repo for scripts so they can be hosted anywhere

📝 Detailed description

Add the ability to repoint the repo using the UI so that a user can clone the current repo and use their own clone. This allows users to develop scripts that can be merged at a later time with the main community scripts repo, or allow them to keep copies of their scripts that they may have made for personalization and still be able to install/update them on their own without necessitating the need for a manual installation.

This might require some alterations to all scripts(this, as well as the install/update scripts), including making the domain a variable in the installation scripts, but would provide flexibility for everyone

💡 Why is this useful?

By adding this, a user can utilize the main repo or provide a custom repo where they can develop/update/maintain scripts that may be publicly usable or privately usable. It can allow developers to build a process and test it without the need to use SSH and/or have direct access to the host since it goes through a tunnel. They could build the process and put it in the repo, then execute it from the UI.

I need to think that through. It is so tailored to our main repo that i dont know if this will be possible to work with any repo, as we use the same scripts and backend stuff. But i will keep it in mind.
