[53.0.0_maintenance] Fix CI

[alamb]

Which issue does this PR close?

• Part of Release arrow-rs / parquet minor version 53.4.0 (Jan 2025) arrow-rs-object-store#30

Rationale for this change

Rust 1.84 was released yesterday: https://blog.rust-lang.org/2025/01/09/Rust-1.84.0.html

It

1. introduced some new clippy lints that fail on the 53 maintenance branch.
2. Renamed the wasm target (see https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html)

What changes are included in this PR?

1. Ignore the clippy lints (they are fixed for real on main but there is no reason to potentially destabilize 53 with code changes)
2. Update the CI to use the new wasm names

Are there any user-facing changes?

no
