chore(deps): update wasmtime and rust toolchain (#59)

Use latest stable release of Rust. This is required to build newer
versions of wasmtime.

As a result of the update, the resolver version to be used has to be
specified at the root level of the project. This is required to avoid
clippy warnings.
