Feature request: `cargo pgrx init/make world-bin` enable parallel build

[SteveLauC]

Hi, I just initialized this tool on one of my Linux machines, cargo pgrx init --pg17 download takes roughly 3 minutes, looking at the source code:

https://github.com/pgcentralfoundation/pgrx/blob/3ea09af490c2063460a36b7c611f661230f89fc2/cargo-pgrx/src/command/init.rs#L468-L496

We are not building Postgres in parallel, any reason behind this?

Please enable this feature, its painful. I am trying to docargo pgrx initand every time it get stuck in some version compilation.
