Proposed change*

This PR refactors the way Blueprint Changelogs are written. Instead of being input in the mdx doc file for the blueprint, structured json changelogs are placed aside the blueprint yaml file.
Then, a React component in the docs website fetches the changelog file for each blueprint, and renders the Changelog in the blueprint page.

This PR includes no functionality change.

Checklist*

• I followed sections of the Contribution Guidelines relevant to changes I'm proposing.
• I properly tested proposed changes on my system and confirm that they are working as expected.
• I formatted files with Prettier using the command npm run format before submitting my Pull Request.
