Add minor protocol version to debug log message.
The minor version is incorrectly masked with octal `0700`. It get the false minor version(always zero). The true mask is to use hexadecimal `0x0700`.
To solve the protocol violation issue. The neo4j-omni always serializes `DateTime` to the modern structure defined in Bolt 5.0. The Bolt 4.x version cannot unpack it. However, the Bolt 4.4 version may unpack the Bolt 5.0 `DateTime` with a "utc" `patch-bolt`. I just try to use this to solve the problem at least in Bolt 4.4.

There was a problem hiding this comment.
In the default configuration, Bolt 4.0 is still preferred, so #22 will continue to be a problem.
I’d say this patch should also change the default supported versions from 4.0 to 4.4 (in client_config.c).
