[Feature Request] Button or script to "compile" our whole comfy installation into a zip or similar.

### Feature Idea

The idea is that sometimes updating to new versions of comfy breaks lot of custom nodes and other stuff. Simply having a new version of a library availabile can break everything, even if comfy itself hasnt updated anything, the simple presence of the library in the req.txt will make the program get latest library, a piece of code is change, for example inf changed to Inf (capital letter) and all fall appart.

Before doing updates, it could be great to have the posisbility to "save" the state of our current installations, and have the packaged into archives similar to the "releases" packages of comfyUI here.

This is great when we have finally obtained our perfect environement with all custom needs we want, and we want to try new updates without risking losing everything.
