Github Actions: Deploy docusaurus on pull request from Prototype

[basplijnaer]

Depends on

• Github Actions: Deploy docusaurus on pull request from Ampersand repo #1316
• DocuGen repo: Setup initial Docusaurus website #1318

Problem Definition

The same as #1316 for the prototype repo. Within the workflow, now not only copy the docs directory of the Ampersand repo, but also the docs directory of Prototype. In the one-pager, these directories should co-exist. Maybe scaffold pages are required to make this happen. If so, these could be created and stored inside the new repo.

Tasks

• create a development branch.
• Rename the doc directory to docs.
• Make the workflow also trigger on a commit of the development branch of the Prototype repo.
• Document what you do
