[GS] Add Machine Learning deep links to navigational search

[joshdover]

Meta issue: #72680

In #83380 we added support for applications to include a searchDeepLinks property on their core.application.register call which feeds into the navigational search feature.

Machine Learning should add this property to add deep links for their key locations to search. In most cases, this should be adding an array with the name of the location and a URL path to the route in your app. See the documentation for this API for more info. Some things to consider:

• The title for each link should be localized
• The path for each link should be relative to your application's appRoute. Base path does not need to be included.
• If there are locations that are only conditionally available (for example, due to licensing or feature controls), you can utilize the appUpdater$ API. See the example in the Stack Management app.

New links to add

• Machine Learning
  • Overview (same entry point as Machine Learning app)
  • Anomaly Detection
  • Data Frame Analytics
  • Data Visualizer
  • Settings
