refactor(tc): use the example CCA platform token from iat-verifier

In [1], the example CCA platform token has been updated to fix a small
problem with the description of one of the software components, and to
provide a more realistic breakdown of the expected components in the CCA
TCB.

This change replaces the static CCA platform token in the Total Compute
platform.
