feat: options to configure local registry

[tthvo]

Fixes #76

Description

Add options to configure an insecure local registry. An example workflow file can be:

name: Create Cluster with Registry

on: pull_request

jobs:
  create-cluster-with-registry:
    runs-on: ubuntu-latest
    steps:
      - name: Kubernetes KinD Cluster
        uses: helm/kind-action@v1
        with:
          registry: true
          registry_name: my-registry
          registry_port: 5001
          registry_enable_delete: true

Does this look alright?

seems ok, just need to revisit the local registry env var to follow github actions best practices
