 If this action is called when a `pull_request` is `opened` or `syncronized`, then the example will **upload** the specified folder (`build-directory`) to a folder named `pr-previews/PR-123` on the S3 bucket (`myS3Bucket`). The action will exclude any files that start with the default `pr-previews` prefix. The action will not invalidate the cloudfront cache.
