README Addition

[natereid72]

Can we add requirement for Kubernetes API server version =>v1.23 to the README?

Feel free to open a PR with this contribution @natereid72, along with the explanation/details for why that version is needed :)

I'll close that PR and open a new one tomorrow. Need to switch laptops to sign.

idk, @jbw976 we may need to sync tomorrow on this. I signed it but DCO still showing issue with not signed,

Since this is an AWS provider, I assume a lot of people (like me) will be running it on EKS, which only supports up to Kubernetes 1.21. I think a recommendation of 1.23 would be fine, with an explanation of what the issue(s) are with earlier versions.

ok, replaced previous PR with #167. Git amend didn't seem to fix the sign-off issue in previous PR. Added statement on requirement and brief reason.
