Allow to override extension by introducing plugin weights / priorities

Postponed until ✨ Allow to override extension by introducing plugin weights / priorities Active is in.

Hey Pieter Frenssen.
I think we have something similar. Did you check https://git.drupalcode.org/project/graphql/-/commit/4f92c531593465898b20... ?
Based on the plugin's weight the full graphql file content has to be replaced.
IMHO, if we can override the AST tree content part it could be much more flexible.

This is no longer postponed. ✨ Allow to override extension by introducing plugin weights / priorities Active has been fixed.
