Fix styling in documentation for `suspicious_xor_used_as_pow` lint

There was a tab after the three leading slashes which caused the contents of the "Why is this bad?" section to be rendered as a code block.

**Before:**

**After:**

<img width="520" alt="fixed" src="https://user-images.githubusercontent.com/4869194/214985561-87255196-008c-4a1c-8cc8-c54b337d22a2.png">

The file still contains a lot of tabs but they don't affect the documentation.
