login failing for Amazon ECR public repository

[ravikishore1979]

docker.withRegistry fails to login for a public repository but works with the private repository.
Can we use this plugin to login to the Amazon ECR public repository?

I am facing this issue too. Pushing to Public ECR registry with this plugin doesn't work. Works fine for private ones.
I could not find any clarification regarding this in the readme either.

Public and private ECR repositories use completely different API endpoints and IAM objects (ecr:GetAuthorizationToken vs. ecr-public:GetAuthorizationToken), so this is no surprise. One could probably extend this plugin to support both (with a new "mapping prefix"), but it won't work out-of-the-box.

I'm not interested in implementing this myself, but I might merge an extension to this plugin (preferably with tests & without too much code duplication)
