Linking the Error Correction Zoo to how to make codes in Qiskit-QEC

[dsvandet]

For as many entries as possible in the Error Correction Zoo have links that send you to a website (starting with the qiskit-qec github site say) that show how to create that particular code or set of codes in Qiskit-QEC.

The links in the Zoo should be something like

https://qiskit.org/documentation/qec/goto?code_id=code_id

that takes someone to the specific page associated with code with code_id=code_id. As we do not have this specific site up at the moment, in the beginning it could be something like;

https://github.com/qiskit-community/qiskit-qec/tree/main/docs/zoo/code_id.md

where we just have all the code in the same zoo folder. When we update this link the links on the Zoo can then update accordingly.
