clearer-documentation-on-inline-diffs

What does this MR do?

Makes the documentation on inline markdown diffs a little clearer and gives an easy target to copy

Are there points in the code the reviewer needs to double check?

• Maybe the bullet points can be deleted as well, as the examples are within a codeblock
