Brief Description of Fix

Currently, the recommended approach for reviewing documentation updates is to build the docs locally. This may still be the recommended approach, but a note should be included that lets developers know that they can preview the docs from the PR checks as well (with the new netlify inclusion).

I would like to propose a change, such that now the docs have examples on how to use the netlify doc previews from a PR.

Relevant Context

• Link to exact file to be edited
• Maybe we want to add a line to the CONTRIBUTING.rst files as well? 🤷‍♂️
