chore(docs): Fix link in the Data Types page (#4527)

# Description

## Problem\*

Existing link in the [Data Types
page](https://noir-lang.org/docs/dev/noir/concepts/data_types/) to the
generics page opens
https://noir-lang.org/assets/files/generics-ff7aa43d69e6cca523a1f2e74064a062.md
in a separate tab, instead of the page in the docs.
