Docs: salesforce compliance adjustments

[lukegalbraithrussell]

Summary

Adding a footer with the required info. Pulling it and the navbar into separate files so I can add a github action workflow to update the files in one repo and it propogates to the others

Testing

You could git clone then cd docs, npm i and npm run start to open it locally. Don't think its necessary since this is the exact same as PRs in other repos
