versioning `Cargo.toml` vs env var VERSION

[isabelroses]

There are conflicting versions in the Cargo.toml here

rsky/rsky-pds/Cargo.toml

Line 3 in 902f5cc

version = "0.1.1"

and

rsky/rsky-pds/src/lib.rs

Line 137 in 902f5cc

let env_version = env::var("VERSION").unwrap_or("0.3.0-beta.3".into());

Perhaps env!("CARGO_VERSION") would be better?; unless theres a need to override VERSION easily?

CARGO_PKG_VERSION works to replicate the Cargo declared version; I don't think that's the intent? It didn't change my build with the linked ticket #134 either.
