test(test-tooling): fix flaky rustc-container-target-nodejs.test

The problem was that the Rust compiler version we were using
(v1.52.x) seem to have gotten outdated and it would no longer
work with wasm-pack.
To provide a fix I upgraded the base image of the container to
come with Rust v1.57.x and now the build error[1] is no longer
present and the test case is passing with the new image that was
pushed to ghcr.io.

The image tag this was pushed as is:
ghcr.io/hyperledger/cactus-rust-compiler:2022-01-12-15d4793c---fix-1646
which is now also the default tag that the RustcContainer class
uses in the test-tooling package.
