This patch removes the dependency on chromedriver entirely from the package. Now we check for the environment variable and if it isn't present we fail with a meaningful error message. Since this is only used in tests, it only impacts developers working in the project and not consumers of it.

The contributing documentation has been updated to include information on how to get the needed binaries installed and configured.

Upon opening this PR, the Prettier check was failing. The reason for this was the dependencies were installed before node was setup on the version we run on locally. So Prettier was then expecting a newer node version then what it should be operating on. To fix this, I swapped the order of node-setup and Install Dependencies in the formatter workflow.
