[Trigger Actions UI] Improve alert instances view by having instance name, tags

[shahzad31]

Describe the feature:

Alert UI has a nice instance view which displays alerts instances as a table,

right now instance can only an id , which is then displayed in table, and since that instance id is also used in api, it can't contain for example a url value, i propose that we allow adding few additional fields into instance, like name and tags, so that instance can become more identifiable for user to act like muting them.

Describe a specific use case for the feature:
User can identify alerts by instance id, but in some cases those are not really useful, this is in part motivated by this user enhancement request here #80932

I think this is a DUP of #64268, which we ended up closing. Happy to keep that closed and have this open as the new version of the enhancement request, especially as it suggests adding even more data to instances (eg, tags).
