Add GitHub workflow to build and publish Docker image on the GitHub container registry

[nikstuckenbrock]

Hey,

as mentioned in the title, this PR adds the functionality to automatically create a Docker image when a new release is created. This image is then published to the GitHub container registry of this repository. I think it's a more easy way to use and install the navigator. Let me know what you think.

For implementation i sticked to the official documentation from GitHub.

Here is an example pipeline i run in my fork and you can find the published image here.

Hello, and thank you for the contribution. Please refactor these changes to align more closely with our other Docker workflows; namely the ATT&CK Workbench REST API publish.yml workflow.

There are some notable differences in biz logic:

• Should run push to branches master, develop, as well as push git tags v*.*.* (semver) as opposed to any wildcard value (*)
• Should only generate Docker metadata tags/values for the following:
  • latest for branch master
  • develop for branch develop
  • vX.Y.Z for git tag event (git tag must follow semver format)
• Should not operate on PRs (set push: ${{ github.event_name != 'pull_request' }})

Our current Docker workflow is not tethered to GitHub Releases, so the workflow should be decoupled from create-release.yml and moved to a new workflow file.

Hey @seansica,

thanks for your feedback. I simply copied the workflow from the repo you've mentioned. Let me know if this resolves your change requests. Furthermore, do you know when the next release is planned so I can you a tagged image? Thanks in advance.
