Website publish action (#1358)

## Description

Triggered manually from actions page using [manual trigger](https://github.blog/changelog/2020-07-06-github-actions-manual-triggers-with-workflow_dispatch/).

@vkamra ~We will need `WEBSITE_S3_BUCKET` and `WEBSITE_CF_DISTRIBUTION` in `Production` env for this to work.~ If you could add the s3 and cloudfront details to to GitHub secrets, I'll switch to using the secrets instead.
