VM security type not set in ARM when specifying enable-secure-boot

### Describe the bug

In Azure CLI v2.65.0 (and previous versions as well) it is not possible to create a VM where the following two options are defined:

`--security-type Standard --enable-secure-boot false`

This is identical to the issue reported in https://github.com/Azure/azure-cli/issues/28397
