Closes #6

Features

Adds a script which can be run with npm run build:locales. This scans all mcdoc files and writes to files: /locales/keys/en.json and /locales/docs/en.json.

Tasks

• Use Spyglass to parse all .mcdoc files
• Process the ASTs to list all keys and all doc comments
• Transform keys to human readable strings
• Create GitHub workflow to run the script and commit on push to main
• Tested the workflow in private repo

Future work

• Allow overwriting keys English locale
• Detect field renames by comparing the previous locale
