Updated dependencies, removes remove_dir_all, which is vulnerable (#…

…2685)

After this, we are still waiting for `indexmap` & `dashmap` to provide the new `hashbrown` to reduce duplicate dependencies, and for `criterion` to remove `clap` and release a new version. We're also waiting for a new version of `icu_datagen` that bumps the `zip` dependency to avoid a potential vulnerability. Ideally, they would also bump the `simple_logger` dependency, which is pretty outdated. In any case, `simple_logger` still uses an unmaintained `atty` dependency.

Relevant issues:

 - unicode-org/icu4x#3150
 - bheisler/criterion.rs#599
 - borntyping/rust-simple_logger#74
