docs: Apply consistent md code block indentation

[doolio]

Note, I did not adjust the auto-generated text code blocks in configuration.md as I presumed any changes would be overwritten. To apply the same style for those blocks I presume it would have to be applied from where those blocks are generated. But I was unsure where that was.

Is this enforceable by one of our pre-commit tools for linting markdown? I'm not sure I really care either way but if it's not checked by a tool it's probably not going to remain consistent.

This PR relates to the inconsistency I highlighted here and it was explained later that it is required or did I misinterpret that explanation. @charliermarsh also added indentation to code blocks (commit 231aff0) in another PR I submitted so I presumed that was the preferred style.

But in reality my understanding is indentation is not necessary if the code block is fenced which they all seemed to be. So if anything the indentation should be removed from all code blocks, no?

Edit:

I don't know but if so then it doesn't seem to enforce it consistently whichever style is preferred.

did I misinterpret that explanation

yep, I specifically said that

[...] indented code blocks are only used for tabs because that's the syntax they require [...]

Charlie's commit specifically corrects that

I think this PR can be closed 👍

Ah I see. Thanks for the clarification.
