The capitalization is correct in this case, so we will be leaving the docs as is. I'll go ahead and close this PR.

@cmwilson21 but i was working on a repo, and for me, it was failing with a -S and worked fine with a -s

[cmwilson21]

@shekhar-chauhan Thanks for providing this extra information. Per official git documentation, both the -s (sign-off) and -S (signature) flags work on commit messages. The -S flag fits the signature article. 👍

Thanks again for your interest in improving the GitHub Docs! 💛
