Subject: [PATCH] chore: Remove dependency on home crate, use std instead

We have CI problems related to the home crate, so I looked up what
that crate is doing.
In it's description it states that Rust 1.85.0 fixed the Windows HOME
problems and users are encouraged to use std instead.

So I did exactly that, as kube's MSRV is 1.85.0.
