✨ feat: Add logic to push 'latest' tag for Docker images based on release tags

[Impre-visible]

This pull request updates the Docker image publishing workflow to automatically tag images as latest when the current release matches the latest GitHub release. The workflow now determines if the pushed tag is the most recent and, if so, pushes an additional latest tag alongside the versioned tag.

Key changes to the Docker publish workflow:

Automated tagging logic:

• Added logic in the prepare job to compare the current tag with the latest GitHub release tag using the GitHub CLI (gh). If they match, a push-latest flag is set to true. (.github/workflows/docker-publish.yml)
• The push-latest value is now output from the prepare job for downstream steps to use. (.github/workflows/docker-publish.yml)

Image publishing enhancements:

• In the image publishing step, if push-latest is true, the workflow adds the latest tag to the image alongside the version-specific tag. (.github/workflows/docker-publish.yml)

Workflow cleanup:

• Minor formatting and whitespace cleanup in the build steps for readability. (.github/workflows/docker-publish.yml)
