fix : Update async-cli package to use ES modules

[Recxsmacx]

Fixes #1698

Update async-cli package to use ES modules instead of CommonJS.

• Update tsconfig.json files:

  • Change module to ESNext in tsconfig.json, assets/create-glee-app/templates/default/tsconfig.json, and assets/create-glee-app/templates/tutorial/tsconfig.json.
  • Update moduleResolution to node in the same files.

• Update package.json:

  • Add "type": "module".

• Update import/export syntax:

  • Modify import statements in src/commands/bundle.ts, src/commands/convert.ts, src/commands/generate/fromTemplate.ts, scripts/fetch-asyncapi-example.js, scripts/releasePackagesRename.js, and src/index.ts to use ES module syntax.
