Update givenergy_givtcp.yaml (#1405)

Corrected line 74.

Config only listed option as "inverter", should have been "inverter type:" 

Line 75 now list inverter type as "GE".

This resolves an issue in the Predbat log that was saying stating "Warn: Inverter 0: inverter definition is not a dictionary".
