UI no longer wraps objects/arrays with string identifiers when passing parameters to a SQL Server Stored Procedure

### Describe the Bug with repro steps

Previously, in the (still better) old UI, when adding an element to a stored procedure it would automatically stringify it by wrapping it in '{}' as the stored proc would expect this to be a string (NVARCHAR(MAX) in the definition of the usp).

Now you need to do that either by wrapping it with string or go to the code and do it manually.

When doing it with the accolades in the code, it quite often breaks the designer and the activity.

Additionally it seems you are no longer able to select the 'Body' of an activity in the UI when populating said parameter.
