handle viewing sample dashboards on default dist

[LeeDr]

Summary

Fixes: #55795

Fixes sample data oss tests so they can launch the sample Dashboards regardless of an OSS or Default Dist build (including Cloud). The difference mainly being the View button in the sample data panels in OSS opens the dashboards directly because it's the only sample item. But on the default distribution there are other items that appear in a list so we have to select Dashboard for that method to work the same.

I used isOss, but in Kibana it's really "is there more than one item". So if we add some other sample data app to OSS, we'll have to fix this differently.
