Add Practice Exercise: `grep`

[0xNeshi]

Problem specification: https://github.com/exercism/problem-specifications/tree/main/exercises/grep

TODO:

• generate the exercise with ./bin/fetch-configlet && ./bin/configlet create --practice-exercise grep
• check if any of the existing tracks (examples below) implement the exercise and you can reuse the implementation:
  • Go: https://github.com/exercism/go/tree/main/exercises/practice
  • Rust: https://github.com/exercism/rust/tree/main/exercises/practice
  • Python: https://github.com/exercism/python/tree/main/exercises/practice
• use exercise's canonical-data.json to see which test cases to implement: https://github.com/exercism/problem-specifications/blob/main/exercises/grep/canonical-data.json

@Falilah ~go for it!~ Just realized this exercise is out of scope, as Cairo was not built to work with files. Apologies for the confusion, and please feel free to pick another exercise!

And thank you for your numerous contributions, you're truly awesome :heart_on_fire:
