fix(Workflow): Search bar to select object is not working as expected (#16255)

Fixes Issue: #16188

**Bug:** 
Object Selection Dropdown was not working correctly when searching by
object's name.
This was happening only when `Search Records` action is selected. 
Other actions(Create, Delete, Update, Upsert) were working
correclty(object search was working).

**Reason:** 
`Search Records` action uses `WorkflowObjectDropdownContent` component
which only filters based on `nameSingular` field in metadata (and doesnt
search based on lable text).
All other record action uses the `Select` component which filters by the
label property (set to `labelProperty`).

**Fix:** 
Updated the filtering logic of `WorkflowObjectDropdownContent` component
to match the search text with label field also.


I could't find any unit tests for the `WorkflowObjectDropdownContent`
component (or any other component in workflow module). Let me know if I
missed it and if tests need to be added for this.
