Documentation

• Have you proposed a file change/ PR with appium to update documentation?

There is no ViewMatcher doc at all currently, though it seems to be supported in espresso driver, so not sure what C# docs would be helpful here.

Integration tests

• Have you provided integration tests to pass against the beta version of appium? (for Bugfix or New feature)

Details

Looking to add support for decorating some android views with automation identifiers that get set in View.setTag(R.id.automation_id, "idvaluehere") and using ViewMatchers to select views based on those values (ie: onView(withTagKey(8675309,is('idvaluehere'))) with a selector such as:

{
  "name" : "withTagKey",
  "args" : [ 
    8675309, 
    { 
      "name" : "is",
      "args" : "idvaluehere"
    }
  ]
}

@akinsolb would be helpful for some work around UI Testing infrastructure for MAUI :)

@Redth Will trigger the release now. It might take a while for it to appear in nuget due to indexing
