Send a File or Text Message to Discord (custom define color, username or avatar)

Allows overriding username, avatar, and embed color, enabling branded notifications as shown in the examples with custom color and username.

Can send multiple files such as images or logs in a single step, useful for sharing build artifacts or reports directly in Discord.

Supports separate webhook ID and token inputs to avoid exposing full URLs in workflow logs, enhancing security for sensitive channels.

Built on Docker for consistent execution in GitHub's Linux container environment, reducing compatibility issues and ensuring it 'just works'.
