Add option to set DAPR protocol for Container Apps

[MKMZ]

Currently, the ARM Template has the option to change the protocol used to communicate with the DAPR sidecar. Possible values are: 'http', 'grpc'. The default value is: 'http'. I want to ask to add an option to change the DAPR protocol to 'grpc'.

This sounds like a good feature to add - I'm happy to support anyone who wishes to raise a PR for this.
