Sync needs extra permissions, like ListObject, to function, but the keys
we have are the most minimal that are possible. Instead, we should copy
local files unconditionally.
The release job will do an npm publish and a github-release.
It's based on videojs/.github/github-release.yml.
The new version is published as `next` and requires to be promoted to
latest manually.
The deploy job, should do an aws s3 sync to upload the files to S3 for
us. It uses a Github Environment secrets. This is so that we can require
a user to approve the CDN upload.
