Description of your changes

This is how the latest providers are built to simplify the build process. In addition, marketplace is the default registry now instead of DockerHub since it's free for all Crossplane packages.

I have:

• [x] Read and followed Crossplane's contribution process.
• [x] Run make reviewable to ensure this PR is ready for review.
• [x] Added backport release-x.y labels to auto-backport this PR if necessary.
