Create new auto translation github actions workflow

[Bruce-Moe]

• Added the workshop AI translation tool repo as a submodule to the main workshop repo
• Create a new Github actions workflow for automatically running the workshop translation tool in pull requests
• The workflow will automatically run whenever a pull request is created that contains changes to files in the "workshops/content/english" folder, and will only generate translations for the changed workshop files
• The workflow will not overwrite existing translation files. It will only generate translations for languages where the translated file does not already exist
• The workflow will automatically commit and push the translated files to the pull request so that the developer can review/edit/delete the changes
