Startup Debugging Logs

[JamesIves]

Noting down some ideas I have on startup debugging. When the container starts, I'd like to see:

• The image if used
• If no image is used, something that states that its a custom image(?)
• The games engine version the image was built with (if available)
• Links to the GitHub Discussions board for support
• Any other details that may be helpful to support users

I've added an update in 1.2.0 that handles this: https://github.com/JamesIves/hlds-docker/releases/tag/v1.2.0
