George Kalpakas 1b38b413de docs: fix indentation of code snippets in the "Cheat sheet" guide (#41051)
Previously, the indentation of code snippets in the "Cheat sheet" guide
was done using regular spaces. However, leading whitespace is ignored in
HTML elements (by default), which resulted in the identation being lost.

This commit fixes this by using the ` ` HTML entity for
indentation, ensuring the code snippets are easier to read.

Some examples:

Before: ![cheatsheet code indentation before][1]
After: ![cheatsheet code since PR 40944][2]
