Subject: [PATCH 07/12] Documentation: kvm: tdx-tdp-mmu: Use literal code block for EPT violation diagrams

EPT violation diagrams aren't inside literal code block, which trigger
"line block ends without a blank line" warning. Since these diagrams
aren't meant line blocks, use literal code block instead.
