Auto update api docs and upload api docs to gh-pages

[cewert]

I had to change the theme (again) for the auto-commit action to work right. The theme we were using was generating a uniqueid every time the docs were built and then updating all the html files even if there were no changes.

I also added a workflow to deploy the api docs to gh-pages but I was unable to test that on my fork 🤞

Changes

• Recommend brightscript jsdoc vscode extension - this allows devs to auto create a function definition using a vscode shortcut (ctrl + alt + /)
• Switch to ink-docstrap jsdoc template
• Create build-docs.yml workflow
  • Only run for unstable branch pushes
  • Runs npm run docs and commits any changes to the unstable branch
• Create deploy-api-docs.yml workflow
  • Only run for unstable branch pushes
  • Deploys everything in the docs/api folder to gh-pages
• Create docs/api-docs-readme.md file to be used as index page for gh-pages (new theme had a blank index)
• Exclude the docs/api folder when searching with vscode
