Transition from Email.GetSignedByCertChain to Email.LastSignerCert

Provides instructions for replacing deprecated GetSignedByCertChain method calls with LastSignerCert. CkPython

# Do the equivalent using LastSignerCert to get the signing certificate,
# then build the cert chain from the signing certificate object.
