feat: Add CI/CD Docker Integration with GitHub Actions

[melton-jason]

This feature brings the "Dockerize" support once only enjoyed by the primary Specify 7 repository to the Web Asset Server.
Primarily:

• If desired, we can now version the Web Asset Server with the same scheme of the Specify 7 releases (vX, vX.Y, vX.Y.Z, etc.)
  • See https://discourse.specifysoftware.org/t/how-to-update-specify-7/2475#p-4782-understanding-docker-release-tags-1
  • That is, if a tag is created following a "release scheme", it will update all corresponding vX.Y.Z image tags on Docker Hub.
• Normal pushes which are not tags and do not match the versioning scheme will push the changes on the branch to a Docker image with a corresponding name

Testing Instructions:

• Re-run all jobs for the Dockerize GitHub Workflow
  • (or optionally) push a branch based on these changes
• Inspect the runtime logs of all Actions within the Dockerize GitHub Workflow
• Once complete, ensure the corresponding branch on Docker Hub has been updated

I'd like versioning to be independent

#41 (comment)

Sorry for any confusion! By sharing the same scheme, I meant only that the versioning process/function is the same. That is, if we create a tag in this repository we can expect the same pushed tags on the specify-asset-service as if we had tagged the Specify 7 repository with the same tag name.

Versioning is independent for each service. If we have a tag v2.0.0 for the Web Asset Server, it is independent from all other services (Specify 7, Webportal, Report Runner, etc.).

For example, if we:

• Tag v7.12.0 on the Specify 7 repository
  • All other services (repositories) will not have any latest v7, v7.12, or v7.12.0 tags pushed or modified
• Tag v2.0.0 on this repository (Web Asset Server)
  • The corresponding latest, v2, v2.0, and v2.0.0 docker images will be pushed to Docker Hub only for the specify-asset-service base image
