Update lazymc to support 1.19(.2)

[jlxip]

I'm using the docker container. My server is on 1.19.2, and I thought changing the MC_VERSION env var and version and protocol in lazymc.toml would make it work. When the container starts, it tries to download a lazymc release with no version, so I'm guessing there's some changes to be made here.

Edit: logs from the container

Apparently it does work if lazymc.toml is altered after the first execution so that the lazymc binary is already there.
