Feature: Use old protocol data to try and connect to a snapshot server.

Is your feature request related to a problem? Please describe.
I'm trying to have my bot join a 25w14craftmine LAN game so I can chat with it.

Error: Unsupported protocol version '1073742068'; try updating your packages with 'npm update'

… but perfect protocol support won't come for a while since it seems blocked on multiple issues in minecraft-data and mineflayer.
However, maybe I don't need perfect protocol support for just chat messages.
So maybe I could have some option to try and act as if 25w14craftmine had the same protocol as 1.21.4? Seems to be worth at least a try.

Even if it turns out chat messages have diverged too much and it may not solve this exact scenario, that option could be useful for future snapshots.

Describe the solution you'd like
An option to use an older protocol even if it seems incompatible.
Lie to the server if needed.

Additional context

No files, tests, or entry points are named in the issue. Begin by locating protocol-version compatibility and connection negotiation, then determine how an option could select an older protocol; done means a client can attempt that connection and the behavior is covered by appropriate tests.
