Update protocol sequence diagram with SetupChannel name change
Diagram is found at https://gitlab.com/lightning-signer/docs/-/blob/master/seq-diagrams/README.md
Other protocol sequence diagram issues: #6 (closed), #7, #8
Pursuant to validating-lightning-signer#401 (closed) and validating-lightning-signer!541 (merged) the protocol sequence diagram needs to have:
- all instances of
ReadyChannel
changed toSetupChannel
- all instances of
funding_locked
changed tochannel_ready
This change was needed because the lightning-dev renamed funding_locked
to channel_ready
well after we were already using the name for a different thing ...
