test: update examples to type: module (ESM)

[MikeMcC399]

Situation

• Cypress projects in the examples sub-directories are mainly configured with cypress.config.js using CommonJS require and no specification of the type field in their respective package.json file

• The Node.js documentation explains in Modules: CommonJS modules

  CommonJS modules are the original way to package JavaScript code for Node.js.

  and in Modules: ECMAScript modules

  ECMAScript modules are the official standard format to package JavaScript code for reuse.

Change

Where necessary in examples sub-directories:

• add "type": "module" to package.json files
• convert cypress.config.js files from require (CommonJS) to import (ESM)
• convert any other CommonJS source files used in examples to ESM
