azurerm_api_management_api - correctly setting the soap API typ… (#5081)

I am not completely sure if the modified block (line 222-229) is 100 % correct.
Not sure if there can be other combinations of those properties.

The change has been tested and verified locally for both soap_pass_through = true and false

Fixes #5080
