Edit working-with-text.md, small wording adjustment

[Kezy-d4]

Because

This is a change to the wording of a sentence under the 'Nesting and indentation' part of the lesson. This change is more fitting since the amount of spaces per indentation is largely a matter of personal preference.

This PR

• Changed: "It is recommended to indent any child elements by two spaces." to: "In our examples, we have indented any child elements by two spaces."
