Build: Implement GitHub Actions for Co-op Translator

[skytin1004]

Purpose

This GitHub Action implementation for Co-op Translator aims to automate the translation of project documentation and images whenever changes are made to the repository. It enhances the workflow by ensuring that all content is consistently translated into specified languages without manual intervention.

Description

The addition of GitHub Actions support allows for seamless integration of Co-op Translator into the CI/CD pipeline. This change is necessary to reduce the overhead of manual translations and to ensure that the latest content is always available in multiple languages, thereby reaching a broader audience.
