What article on docs.github.com is affected?

https://docs.github.com/en/get-started/getting-started-with-git/setting-your-username-in-git
https://docs.github.com/en/account-and-profile/how-tos/email-preferences/setting-your-commit-email-address

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

The documentation on setting commit email addresses
(https://docs.github.com/en/account-and-profile/how-tos/email-preferences/setting-your-commit-email-address)
doesn't clearly emphasize that git config user.name must ALSO be set for commits
to show your username and profile on GitHub.

Users following the email setup guide end up with unattributed commits if they
haven't already configured user.name. The docs should explicitly mention that
BOTH user.name and user.email are required for proper attribution.

@oskolist I think that change is fine, maybe a mention in the "next steps" section at the bottom with a link to setting a username. Conveniently, the "to learn more about using a private email address" line at the bottom should also be erased, and its link instead going at the end of the first paragraph, since the link there currently is self-referential and links back to the same page. :face_palm: It's a fairly simple fix, just placing/moving some links, so I'll add a help wanted label to this, and whoever wants to pick it up can.
