Summary:
I regenerated the documentation that lives at https://instagram.github.io/IGListKit/ via the `scripts/build_docs.sh` script.
This updates the IGListKit documentation from 2021 to 2023, updating references to Meta's open source Twitter account, and ensuring the legally required copyright notices are visible.
