[TwigComponent] Remove wrongly added configuration

This configuration parameter has been added by mistake in 0284c0a#diff-d57f69d9cc81e78af30634d1b88a735542ffb1c98c782269abb604a85b727ce1R189-R191

I checked everywhere in this component and there is no usage of it

(it seems to come from a Stimulus config copy/paste during the 6.4 ~~chaos~~ rush)
