Bug report for compiling, code snippets, templates, etc.

In this part of substrate documentation, you can see the git url as set https://github.com/paritytech/polkadot-sdk.git which is wrong, but should be https://github.com/paritytech/substrate.git. Otherwise you will see the compile error.

Steps to reproduce the problem

Following the docs and code within at the page I attached, you will see the compile error.
