Add docker image publishing to release workflow with tagging (#91)

ci(workflows): add trigger for Docker Publish Workflow on new release
creation
ci(workflows): update Docker image build and push actions to include
version tag
ci(workflows): add support for building and pushing Docker image with
nightly tag

The changes were made to enhance the CI workflows related to creating
new releases and publishing Docker images. The trigger for the Docker
Publish Workflow was added to the create-new-release.yml file to
automate the process of publishing Docker images when a new release is
created. Additionally, the publish-docker-image.yml file was updated to
include support for building and pushing Docker images with version tags
and a nightly tag based on the event payload. This improves the
automation and versioning of Docker images in the CI pipeline.
