The version of the Provisioning API is not up to date

[cecilia-barnhill-cubic]

in the current version of the sdk, the prov api version is 2019-03-31

azure-iot-sdk-c/provisioning_client/inc/azure_prov_client/prov_client_const.h

Line 18 in 6b77538

static const char* const PROV_API_VERSION = "2019-03-31";

the latest version supported by the dps is 2021-06-01

This didn't seem to cause issues for certain types of certificates - the certs generated using the Microsoft certGen.sh were able to provision without issue, but upon switching to production certificates, we received the below json:
{"errorCode":401002,"trackingId":"701c9c8f-e467-47d8-8a01-c805a19ab22a","message":"Unauthorized","timestampUtc":"2024-02-08T18:13:04.331944Z"}
I was able to verify the api version impacted the response using curl and I updated the PROV_API_VERSION, rebuilt the sdk, and have our devices provisioning successfully.
