Deprecation warnings despite using latest version

[JoseDiazRohena]

Hi all. This might be user error but here goes. I'm getting the following error when using this action:

Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: apple-actions/import-codesign-certs@v1. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/.

This is despite my specifying the latest version (v1) in my action.

- name: Import Certificates (macOS)
      uses: apple-actions/import-codesign-certs@v1

I can see that this fix has been applied to the main branch of this repo. So it looks like the right version isn't being pulled down?

Thank you!
