Bento launch: remove experiment

[samouri]

Description

Now that Bento is launched (https://bentojs.dev), we should remove the bento experiment from all of our AMP Components. One example is:

amphtml/extensions/amp-base-carousel/1.0/amp-base-carousel.js

Lines 37 to 44 in 8c34f2d

	isLayoutSupported(layout) {
	userAssert(
	isExperimentOn(this.win, 'bento') ||
	isExperimentOn(this.win, 'bento-carousel'),
	'expected global "bento" or specific "bento-carousel" experiment to be enabled'
	);
	return super.isLayoutSupported(layout);
	}

If we can't do this today, we should come up with a list of items we need accomplished before we can remove the experiment.
