Populate data to drupalSettings to enable Dynamic Code Components

I added more details and what I propose as the data shape.

Note: spend zero seconds on making pageTitle work, until 🐛 Handle adding page title to content Active is in. Hardcode some string for now.

Added some implementation guidance.

#3: We need the page title in drupalSettings.xbData regardless of that. 🐛 Handle adding page title to content Active will enable the page title block to work, but we would like to support building a dynamic code component where users can access the raw page title and add custom markup around it. It was amongst our original goals for ✨ Code Components as Block Overrides, step 1 Active , but we dropped that due to the challenges with page title block. Or maybe what you're saying is that we need 🐛 Handle adding page title to content Active even to be able to populate it in drupalSettings.xbData? 🙂
