Add :latest tag to stable releases for improved user experience

This commit adds :latest tag for stable releases to align with Docker
conventions and best practices.  The :edge tag remains for anything from
the bleeding edge.

Changes:
- Workflow: Push :latest tag for stable (non-prerelease) versions
- README: Update examples to use :latest instead of :edge
- Fix: Correct httpd command syntax in example

Tag strategy going forward:
- :latest → most recent stable release (conventional)
- :edge → bleeding edge builds from main (for early adopters)
- :1.2.3 → specific versions (for reproducibility)
