Editor: Simplify the block bindings HTML replacement logic until the HTML API is ready. 

This changeset modifies the block bindings HTML replacement logic to use a hardcoded list of selectors based on the block and a regex to substitute the inner content. The previous logic was too complex because the HTML API does not support CSS selectors yet and it does not have an official way to modify the inner HTML. This made it difficult to understand, iterate on it and add new functionalities.
As it will be solved in the future once the HTML API is ready, it is better for now to keep a simple hardcoded version that is easier to understand and iterate on.

Props santosguillamot, gziolo, petitphp.
Fixes #61351.
