Describe the bug

To enable support for "Authorization Code + PKCE", the api spec on grantTypes should add support for authorizationCodeWithPkce. This has been supported by the Azure Portal for quite some time already.

Expected behavior

Should be able to set grant type "Authorization Code + PKCE" on the OAuth 2.0 client for the APIM Developer Portal

Actual behavior

grant type authorizationCodeWithPkce is not supported by the spec yet

Reproduction Steps

Trying to set this grant type via Terraform, getting the following error:

Environment

Terraform: v1.12.0
AzureRM provider: v4.28.0
