Is the example in the README correct?

[AdamGagorik]

I have tried the example in the README in a workflow.

- name: Use Docker in rootless mode.
  uses: ScribeMD/rootless-docker@0

I observe the following error:

Error: Unable to resolve action ScribeMD/rootless-docker@0, unable to find version 0

Works if I am more explicit on the release tag.

- name: Use Docker in rootless mode.
  uses: ScribeMD/rootless-docker@0.1.1

@AdamGagorik, thank you for reporting this rather glaring issue. I misinterpreted GitHub's docs to suggest that GitHub Actions understands semantic versioning:

Using the specific major action version allows you to receive critical fixes and security patches while still maintaining compatibility. It also assures that your workflow should still work. ~ jobs.<job_id>.steps[*].uses

However, if users want to be able to reference a major version, the action maintainer has to tag it themselves. I personally feel most users will benefit from pinning a specific version so that they don't need to worry about a dependency breaking them. Dependabot can automatically update these version numbers as often as desired, which seems safer than depending on a major version. I updated the README to show a specific version instead and have filed github/docs#17071 requesting a clarification of GitHub's documentation.

github/docs#17776 was recently merged, clarifying the upstream documentation.
