Fix packaging issues

[KCarlile]

Background

There's a complicated issue related to deployment, references, Windows not being able to handle symlinks, etc. that is causing an issue. This ticket aims to solve that issue through package bundling and rearchitecture of the projects file structure.

Acceptance Criteria

• [x] The project file structure is rearchitected to meet the needs of the bundler and deployment
• Package bundling is added to compile the GDJ JS files into one JS file in the root
  • This was abandoned, for now
• [x] Local testing works without the need for manual intervention on *nix and Windows
• [x] Demo deployment works
  • [x] demo-hosting.yml GitHub Action/workflow is updated as needed
• GitHub NPM package building works
  • release-package.yml GitHub Action/workflow is updated as needed
  • This was abandoned, for now
• [x] All documentation references to file paths are updated
  • Most of the documentation that would be impacted has not yet been merged into development or main or it was created as part of this issue
• [x] Build documentation is updated

Approach

• Try using webpack.js.org for bundling src/*.js files into one guitar-diagrams.js file in the root
  • This may be a solution, but it was too complicated to go straight to this
• Reference the src/*.js files from the docs/examples/index.html file
  • Consider moving examples/ out of docs/ if this helps
• Update GitHub Actions as needed
• Test locally, with deployment, with demo hosting, and with Windows

Notes

There is some overlap with the code pushed in this issue and the code that would be pushed in #30, specifically in the code-owner-docs.md file.
