feat: show sobject type for dml

[lcottercertinia]

Is your feature request related to a problem?

The first think I usually look for (when checking DML) is the object type and it often just says SObject (from the list type). We very rarely use mixed DML.

Describe the solution you'd like

so how about parsing it from the trigger type if present?
