Ensure that protocol version has increased

[staffik]

Protocol version should always increase by one in each release.
If no new protocol upgrades were introduced in the last release cycle, you should make a commit to master that bumps the version anyway.
Example: near/nearcore#8803
Example updates STABLE_PROTOCOL_VERSION, genesis_config.json in jsonrpc-tests, and hardcoded hashes in simple_chain:build_chain (the instruction on how to do that are written in the test code).
