chore: build noctilucent WASM library in a container (aws#26123)

Due to the addition of noctilucent to cdk, contributors needed to download rust/rustup to be able to build the cdk.

This uses the pre-existing dependency on Docker/Finch to containerize the process in order to not incur any further dependencies for contributors to manage.
