I came up with a stopgap that'll allow us to retain those old versions until we can work out the S3 archive. GitHub runners come with some stuff we don't actually use, so a little pre-cleanup and we've gained roughly 10Gb of extra disk 👍
https://github.com/apache/airflow-site/pull/741 If that looks good and we merge it, we can revert this morning's revert.
