DYN-7206: Improve list of selected ids when long

[twastvedt]

Purpose

When a user selects elements from Revit in a Dynamo Player script, the ids of the selected elements are listed in the Player UI. However, to avoid an overly long display, only up to 20 ids are shown. When a user selects more than 20 the list is confusing because no indication is given that the list is partial, except that its length does not match the total count shown.

This PR adds an ellipses at the end of the list if it does not list all the selected elements. It also adds commas between element IDs.

Reported in testing here.

This is ready to merge @QilongTang. I reran SelfServe, it succeeded. I saw a note of yours in Slack that that doesn't update the build status here for some reason? Can we disable protection in order to merge this? Thanks!
