Swap SYNCED and READY columns in output

[bobh66]

Description of your changes

Crossplane creates CRDs for Claims and Composites with the additionalPrinterColumns "SYNCED" and "READY" in that order.

This PR modifies the code generation to use the same order of SYNCED and READY instead of the current READY and SYNCED.

Fixes #359

I have:

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

How has this code been tested

Generated the Upbound provider-aws using these changes and confirmed that the CRDs were generated with the SYNCED and READY fields in that order

Thanks @bobh66 for the change. There's a slight possibility that there might be shell scripts that depend on the current order of the READY and SYNCED columns but I think it's better for us to align with the core Crossplane resources and I would not consider such scripts as following the best practices. I will mark the PR as breaking, treating the kubectl output as part of our contract, and it should be fine if we mention the change in the provider release notes.
