Docker Files and Rust Toolchain

[apop5]

Docker files get the Rust Toolchain version by directly accessing the version.njk file through the curl command.

This should be changed to use njk replacements when FileSync is run. The Completion of a PR will cause the Build container image to run, and automatically generate a new docker container image.

As it stands today, changes to rust versions require manually generating a new container build.
