feat: Adds max_healthy_percentage and skip_matching to autoscalin…

…g group (#256)

* Bump provider constraint to >= 5.32.0 since that's when max_health_percentage attribute support was added and allow configuring max_healthy_percentage

* Add support for skip_matching

* Update docs

* Adds max_healthy_percentage and skip_matching to examples; also updates examples to look for Amazon Linux 2 AMIs since Amazon Linux AMIs are already end of life.

* Update AWS provider version requirement in examples
