Source information for Practice Exercises will be stored in their `.meta/config.json` file, in the (optional) `source` and/or `source_url` properties. This commit adds the source information from the corresponding problem-specifications exercise to the `.meta/config.json` file. The new [configlet](https://github.com/exercism/configlet) version will add support for doing this syncing automatically. Exercism v3 will automatically include the source information in the README.md file that is sent via the CLI using the source properties in the `.meta/config.json` file. See [the spec](https://github.com/exercism/docs/blob/main/anatomy/tracks/practice-exercises.md) for more information.
