How this was tested

• Manually:

[07-07|11:26:13.794] ERROR node/node.go:1287 failed to register VM {"vmID": "srEXiWaHuhNyGwPUi444Tu47ZEDwxTWrbQiuD7FmgSAQ6X7Dy", "error": "handshake failed: RPCChainVM protocol version mismatch between AvalancheGo and Virtual Machine plugin. AvalancheGo version v1.11.9 implements RPCChainVM protocol version 35. The VM located at /Users/stephen/.avalanchego/plugins/srEXiWaHuhNyGwPUi444Tu47ZEDwxTWrbQiuD7FmgSAQ6X7Dy implements RPCChainVM protocol version 33. Please make sure that there is an exact match of the protocol versions. This can be achieved by updating your VM or running an older/newer version of AvalancheGo. Please be advised that some virtual machines may not yet support the latest RPCChainVM protocol version"}

@tsachiherman would you want to add the unit test on top of this PR? Or in this PR itself? I'm all for adding more tests.

this PR looks ready.. I'll do it in a separate PR based on this one. ( that way, you could merge this one right away )
