Because whether or not to build a new deps image is based on the SHA of Cargo.lock, changes to the deps Dockerfile will not cause a new deps image to be built. Because of this, the current proxy deps Docker image is based on the wrong Rust version, breaking the build. See #115 for details on this issue.
I've appended a newline to Cargo.lock to change the lockfile's SHA and trigger a rebuild of the deps Docker image on CI. I've also added a comment in the Dockerfile noting that it is necessary to do this when changing that file.
