Acorn - v0.4.1

🐞 Acorn v0.4.1 is here with a few important bug fixes and minor UX improvements! 🐞

What's Changed

Our biggest fix was to address an issue where quay.io could not be used as a registry for acorn images. We've addressed this, but the fix is limited to single-architecture acorn images. If you try to build a multi-arch acorn image via the --platform flag, you still won't be able to push that image to quay.io. We are working with the quay folks to resolve this. See: #951 and #921

Here's the rest of the changes:
