We need Rustc 1.81 for that: https://doc.rust-
lang.org/nightly/core/error/trait.Error.html. But maybe it would be
wiser to backport Rust 1.82 because that's what the Cargo.toml of the
component that fails to build specify: https://github.com/unicode-
org/icu4x/blob/33679069702e826069fe3ebe4198fcee762effd1/Cargo.toml#L111.
