Passing variables to stack file

[francisdeh]

@smashedr Cheers for the impressive work.
Does the current package version support the possibility of passing variables to the stack files during the deployment?
I am thinking of something in the format:

- name: Deploy stack to Portainer
   uses: cssnr/portainer-stack-deploy-action@v1
   with:
      ...
      variables: ''{"TAG" : ":tag-name"}
      name: stack
      file: stack.yaml
      type: file

for a stack file with image of the format

version: "3.9"

services:
  app:
     image: registry.docker.org/app:${TAG:-latest}

I believe that Portainer will substitute stack file variables, with environment variables.

So something like this should work:

with:
  env_json: '{"TAG": "tag-name"}'

With the provided stack file should work as expected.

I actually believe that the Portainer environment is only used to replace variables in the stack file. If this does not work, let me know and I will do a test on my side.
