feat: Add after:spec event

[chrisbreiding]

• Addresses TR-544
• Partially addresses Add new plugin events 'before:spec', 'after:spec', 'before:run', 'after:run' #6665

User facing changelog

• You can now listen to a after:spec event in the plugins file. See the documentation for more information (TODO: link to doc).

Additional details

• The event fires after a spec is run, but before the video for the spec is processed.
• It only fires in run mode.
• The event handler receives two arguments, an object with different versions of the spec file/path, and the results of the spec.

on('after:spec', (spec, results) => {
  // spec:
  //  {
  //    name: 'login_spec.js',
  //    relative: 'cypress/integration/login_spec.js',
  //    absolute: '/Users/janelane/app/cypress/integration/login_spec.js',
  //  }

  // results:
  // {
  //   stats: {
  //     suites: 0,
  //     tests: 1,
  //     passes: 1,
  //     pending: 0,
  //     skipped: 0,
  //     failures: 0,
  //     // ...more properties
  //   }
  //   reporter: 'spec',
  //   tests: [
  //     {
  //       title: ['login', 'logs user in'],
  //       state: 'passed',
  //       body: 'function () {}',
  //       // ...more properties...
  //     }
  //   ],
  //   error: null,
  //   video: '/Users/janelane/app/cypress/videos/login_spec.js.mp4',
  //   screenshots: [],
  //   // ...more properties...
  // }
})
