feat(datasource): add aws-eks datasource

[ivankatliarchuk]

Changes

• added datasource aws-eks

Context

Adding support for AWS EKS version update.

Added aws eks addon data sources https://aws.amazon.com/about-aws/whats-new/2024/12/amazon-eks-access-kubernetes-version-availability/

It should work nicely with AWS EKS addons, and is quite similar to AWS RDS and AWS AMI.

This datasource most likely require it's own versioning, as I have not found similar versioning.

EKS versioning is very close to SemVer but behaviour is very different.

For example cluster version 1.25 must only be upgraded to 1.26. If Renovate provides 1.27, the cluster version 1.25 must be first manually upgrades to 1.26, and only then we can merge Renovate pull request.

I can create versioning before or after this change merged, if it gets merged. Just let me know.

relates to #23410
