⚠ BREAKING CHANGES

• several breaking changes with details below

There are several breaking changes in this release.

1. Replace noDiffForStages with stackSelectionStrategy &
   stackSelectorPatterns
   This uses the native selection stack filtering capability of
   toolkit-lib and should be a more robust option for users to filter
   stacks. stackSelectorPatterns also uses a multi-line input instead of
   a comma delimited string input. To migrate from noDiffForStages to
   stackSelectorPatterns you can do this:

# from this
- name: Diff
   uses: corymhall/cdk-diff-action@v1
   with:
     noDiffForStages: "Stage1,Stage2"
     githubToken: ${{ secrets.GITHUB_TOKEN }}

# to this
- name: Diff
   uses: corymhall/cdk-diff-action@v2-beta
   with:
     stackSelectorPatterns: |
       !Stage1/*
       !Stage2/*
     githubToken: ${{ secrets.GITHUB_TOKEN }}

2. The default diffMethod is changed to change-set to match the cdk
   default behavior. This also changes the IAM Role used for diff from the
   lookup-role to the deploy-role. To keep the old behavior you can
   specify diffMethod: template-only
3. allowDestroyTypes and noFailOnDestructiveChanges input types were
   changed from a comma delimited string to a multi-line string.

# from this
- name: Diff
   uses: corymhall/cdk-diff-action@v1
   with:
     noFailOnDestructiveChanges: "Stage1,Stage2"
     githubToken: ${{ secrets.GITHUB_TOKEN }}

# to this
- name: Diff
   uses: corymhall/cdk-diff-action@v2-beta
   with:
     noFailOnDestructiveChanges: |
       Stage1
       Stage2
     githubToken: ${{ secrets.GITHUB_TOKEN }}
