pi#2778 open report editor

• all the files in docs/ directory are here temporarily until a proper solution is designed to deploy the documentation to Github Pages - this should ideally be a part of the CI. for the time being, the content from docs/ directory is automatically published to github pages. The documentation available is currently coming from 2778_open_report_editor branch but will be amended once this is merged in to main. The code existing in docs/ directory doesn't need to be reviewed as this is what gets generated by jsdoc lib.
• minified library build will be available in the Releases section github. This will be published once this branch is merged in into main
• documentation link - https://panintelligence.github.io/pi-embed-actions/
• using jsdoc and clean-jsdoc-theme to generate documentation
• using esbuild to make a minified js build
• mocha and chai used for js unit testing

This looks really great, I've added a few comments mainly on the documentation side where I think we could improve clarity a little.
