This renames from is-terminal to rustix-is-terminal, and prepares for
rustix support to live in a separate crate.

 As of Rust 1.70, most users should use the [`IsTerminal`] trait in the Rust
 standard library instead of this crate.
 
+This crate is similar to the [is-terminal] crate, but uses `rustix` instead
+of `libc` in its implementation. This allows it to support `no_std` on
+`unix`-family platforms.
