[Network] Example of setting Data property from X509Certificate2

It wasn’t clear to me how to set the certificate Data property given an X509Certificate2. I spent several hours trying to figure this out ultimately cloning the repository to look at the code and examples/unit tests. This is how it’s done:

X509Certificate2 certificate;
...
string base64EncodedCertificate = Convert.ToBase64String(certificate.Export(X509ContentType.Cert));

new ApplicationGatewayTrustedClientCertificate
{
  Data = BinaryData.FromObjectAsJson(base64EncodedCertificate);
}

Nothing else I tried would work. IMO, this is not the most obvious usage. Other things I tried that don’t work but seem more sensible:

new ApplicationGatewayTrustedClientCertificate
{
  Data = BinaryData.FromBytes(certificate.Export(X509ContentType.Cert));
}

new ApplicationGatewayTrustedClientCertificate
{
  Data = BinaryData.FromString(Convert.ToBase64String(certificate.Export(X509ContentType.Cert)));
}

The documentation on how to set the BinaryData property isn’t very helpful unless you already know the answer. For setting certificate Data would be much more helpful to show an example based on an X509Certificate rather than a string “foo”.

@CodyBatt The reason why we expect the input of BinaryData as json is based on how we serialize it, we thought Data could be anything as configured in autorest.md

format-by-name-rules:
  'data': 'any'

But the type of Data is defined as string in Swagger. This is the similar to https://github.com/Azure/azure-sdk-for-net/issues/33804, we are looking into a proper fix for it.
