Description

The toolkit has been updated to check the content-type header and URL for zipped files and intelligently decompress them if it detects a zip. This adds support for that flow to the action.

If a caller wants to download a compressed zip as-is, they can pass the new skip-decompress boolean.

Breaking changes:

• The package has been converted to ESM (to support a similar change in @actions/artifact
• We're changing the download behavior somewhat so we're making this opt-in
