Ability to target elements within theme.json

[slocker3]

My expectation is that the summary element should be available to style via theme.json.

Example:

"happyprime/show-hide-section": {
      "elements": {
	      "summary": {
		      "typography": {
			      "fontWeight": "700"
		      }
	      }
      }
},

Another option is if summary could be turned into a block as well happyprime/show-hide-section-summary. This would probably solve the issues I am having.
