L1-278: Fix synthetic-network repo compilation (#1807)

# Description

Added a custom version of the Dockerfile from the repo of the
synthetic-network tool that uses a more specific version of the rust
compiler. Also removed an ad-hoc fix for node-js images used by the
original Dockerfile.

## Type of change

- Bug fix (non-breaking change which fixes an issue)
