Update dt_utils_get_row.py

[nickpartner-goahead]

current function doesn't allow getting a row from a menu as the function to get the row_id is missing. Changing so that if you put a 0 then it will use current row as the context which is consistent with delete row

Description

row_id is pulled when the reference is set to 0 to make consistent with the validation function, spec and deleterow so that either row id or search is used

Motivation and Context

It makes consistent use of function with others, however is valuable when using a menu item to pull a row which isn't otherwise possible, for example to take a field and add it as an artifact
