Update links for Cairo Regenesis

After the regenesis we should go back and link to these updated starknet docs for appropriate issues: https://docs.starknet.io/documentation/

Start by reviewing the repository for links to Starknet documentation and compare them with https://docs.starknet.io/documentation/. Identify which links are affected by the Cairo Regenesis and update the appropriate references; done means the relevant links point to the current documentation.
