Github giving a deprecation warning when running this Action

[OutpostRyan]

Using this file:

jobs:
deploy:
runs-on: ubuntu-22.04
steps:
- uses: actions/checkout@v2
- name: Deploy Ghost Theme
uses: TryGhost/action-deploy-theme@v1.6.1
with:
api-url: ${{ secrets.GHOST_ADMIN_API_URL }}
api-key: ${{ secrets.GHOST_ADMIN_API_KEY }}

Github action appears to work, but get this message:

deployNode.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: TryGhost/action-deploy-theme@v1.6.1
