Fix: Handle InclusiveNamespaces in digest calculation for SAML Response

The issue was caused by the incorrect handling of the InclusiveNamespaces
element in the digest calculation process. According to the XML-DSig,
the exclusive canonicalization algorithm (XML-EXC-C14N) allows for
canonicalizing XML without including predefined namespaces unless specified
through the PrefixList attribute.
