Removed extra #sign-off line from review table

[ChrisKibble]

Since all commands are author only, having one of the three options called out separately doesn't really serve a purpose.

Hi @ChrisKibble

I think this distinction is important, but it doesn't need a separate row in the table since its the same sign off command. Could you please keep the text as a new line in the first table row? Use the </br> tag to indicate a new line to separate the author vs. non-author scenario.

If a contributor who is not the listed author tries to sign off on a public pull request by using the #sign-off comment, a message is written to the pull request indicating that only the author can assign the label.

Hi @JasonWHowell,

Point well received. Since the same is (probably?) true of all of the commands, what do you think about putting the line below the table as a note that if a non-author tries to use the command they'll receive an error? I'm fine either way, but wanted to throw this alternative idea out there before making the change.

Thanks!
Chris
