Docs: Add sphinxcontrib-mermaid for diagram migration

Add sphinxcontrib-mermaid alongside existing blockdiag/seqdiag
extensions to prepare for migrating live diagrams from blockdiag
to Mermaid syntax.

The blockdiag/seqdiag extensions are abandoned and incompatible
with modern Python. The live diagram content in this repository
will be migrated to Mermaid syntax in a follow-up change, after
which blockdiag/seqdiag can be removed.
