refactor: changed templates to properly fix changes from #868

[Jaskowicz1]

This PR adds missing punctuation from #868, and fixes a spelling mistake in the second bullet point (changing oxygen to doxygen, the fix can be seen below).

Documentation change checklist

• My documentation changes follow the same style as the rest of the documentation and any examples follow the coding style guide.
• I tested that my change works before raising the PR (via running doxygen, and testing examples).
• I have not moved any existing pages or changed any existing URLs without strong justification as to why.
• I have not generated content using AI or a desktop utility such as grammarly.
