This commit updates when the `Error` trait is implemented to account for how in Rust 1.81-and-prior the `Error` trait is always available, even in `core`. This is currently done with detection at build-time of the current Rust compiler version because the MSRV for this crate is below 1.81. In the future when the MSRV is increased, however, the build script can be deleted.
