What article on docs.github.com is affected?

https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site/managing-a-custom-domain-for-your-github-pages-site

What part(s) of the article would you like to see updated?

I set up GitHub pages for the first time and ran into issues because my DNS provider (Squarespace) automatically adds an A record and apex domain for newly created domains. After doing some research it appears this is common for many DNS providers (i.e. Wix, GoDaddy, etc.) so I figured it was worth notating to help other readers.

Additional information

I created a PR for the fix here: #36157
