Updated Earthfile to use latest nightly rust

[eternalfrustation]

Vectorization is only available on nightly rust, as far as i can tell

Seems to work for me with Rust 1.64, without using nightly.

@eternalfrustation it also seems that there is no sh installed by default on alpine.

@giordano that is a good point. The current version on alpine 3.16 seems to be 1.60. https://pkgs.alpinelinux.org/package/v3.16/community/x86_64/rust

@eternalfrustation maybe it would be better to use the rust:1.64-alpine image instead. (see the official rust Docker images)

I have updated Earthfile to install rust:1.64-alpine. Unfortunately, i don't have much experience with docker and earthly, so i don't know if this will work The workflow on my forked repo ran successfully, and rust's mean time was less than C, so i guess vectorization is also working

It worked 👍
