Add a deploy-path action #401
Description
It would be useful to have a sub action which just computes the deploy path and returns it as an output.
From what I can tell you can put multiple action.yml files in the repository. So this could be done by making a deploy-path/action.yml file. This file can then refer to the javascript using relative paths.
The action would be used like:
uses: concord-consortium/s3-deploy-action/deploy-path@v1
The reason for this is so there can be a single build job which includes the DEPLOY_PATH env variable. Then the result of this build is cached and shared by all of the following jobs including the deploy job. In some of our repositories the building can take over 2 minutes. Currently this 2 minutes happens on a build job, each of the cypress jobs, and the deploy job.
