Update docs to publish to calm.finos.org via s3 and configure to use …

Resolves #491

Will remove the GitHub Pages publishing in a later PR assuming this all publishes as expected

First time seeing a .mov as part of a PR - next up is the entire Shrek movie!

Overall looks fine - I worry that if we add more folders into docs that we will forget to update s3-docs-sync.yml and end up publishing things we shouldn't to the FINOS S3 bucket but it's a small risk that is mitigated by proper review processes.

Everything in docs would automatically get included in the sync. The excludes are to prevent the --delete flag from removing other directories we sync (draft and samples); this is because we're copying to contents of docs/build to root rather than into it's own subdir.
