feat: use JSON, templates, npx, and add dry-run support

[avivkeller]

Fixes #3
Closes #185

---

This PR makes a few substantial changes to improve the DX of this tool.

• Moves from INI/env files in templates/ to JSON configurations in configs/, this'll make it easier to edit and parse (See fix(properties): allow quote-less props #185 for an example of dotenv struggles)
• Adds a --dry-run argument, as, when testing this, it's important not to create the issues and notes
• Adds, and relies on, npx-style support. (i.e. npx . tsc or npx https://github.com/nodejs/create-node-meeting-artifacts tsc
  • With this in mind, it makes sense to put the entrypoint in src/, since it no longer really needs to be easily accessible for scripts, it'll be npx-ed.
• Moves from a custom template system to Mustache.
• Uses a dynamic matrix in GH Actions
• Removes obsolete teams (with archived repositories)

The goal here is:

• Improve DX
• Less code to maintain

For example, running npx . web --dry-run produces:

• The comments reference outdated configuration properties. The meetingGroup is now handled by commander in src/index.mjs, and google.clientId is not used anywhere in the codebase. These comments should be updated to reflect the actual usage.
