The Dockerfile already pulls the node:12 image, so there's no need for NVM to be downloaded and installed as well. Removing this speeds up the image build time (making Github Actions go faster)
- Support `apiToken` as an authentication method
- Deprecates `apiKey` and `email`, making them optional parameters and encouraging `apiToken` usage in build logs
- Support `wranglerVersion` for installing a specific Wrangler version for your build
- Per #7, support for `workingDirectory` to run `wrangler-action` in a specific directory in your repo
- Adds a test Workers project under the `test` directory. This is used in the repo's new set of workflows (see below)
- Adds a GitHub Action workflow that:
- Lints `entrypoint.sh` to ensure that the shell script looks correct
- Runs the action with various config options to ensure future pushes don't introduce regressions
