mirror attack_data archive to s3

[pyth0n1c]

Draft of new workflow to push compressed attack data archive to S3. Remove txt file that should not be in the root of the repo.

This is useful in that it speeds up testing, significantly, and avoids error where media.githubusercontent returns an error when trying to download associated attack data.

Note for this to work, we will have to uncomment parts of the workflow as well as add some secrets to the repository with respect to S3.
