feat(cicd,scripts): rely on npx over npm

[avivkeller]

This PR changes the tool from using npm scripts to use npx scripts. This means that the following commands can be used, instead of npm run [...]:

npx . tsc
npx https://github.com/nodejs/create-node-meeting-artifacts tsc
npx github:nodejs/create-node-meeting-artifacts tsc
npx nodejs/create-node-meeting-artifacts tsc

Pull Request Overview

This PR transitions the tool from using npm scripts to npx-based execution, enabling users to run the tool directly via npx commands without requiring predefined npm scripts. The binary name is also updated from create-meeting to create-node-meeting-artifacts for consistency.

• Renamed the binary entry point to match the package name
• Removed all meeting-specific npm scripts (45+ script entries)
• Updated documentation to reflect npx usage patterns
• Refactored GitHub Actions workflow to dynamically discover meeting groups
