Disabling script template is not remembered after editor restart

Issue description

When you disable script template to have an empty script, it will only be remembered until you exit the editor. Next time you will have to disable it again. Pretty sure it wasn't like that when the feature was implemented for the first time.

Steps to reproduce

1. Add script to node
2. Uncheck this
   
3. Restart the editor
4. It's enabled again

It looks like this is not a regression, but an initially unimplemented behavior.

I reviewed and approved the original implementation (#53957) and according to the comments it was implemented at some point. I remember, because I specifically requested it.

Indeed, this was originally implemented, but then was accidentally removed in #59603.

I'm not entirely sure what templates_dictionary is for, but it looks like that logic has been removed as well.

I left a comment in #59603. That PR was wrong.
