Clarify error message when a commit is rejected on website repos
Right now if a committer tries to submit a change on a website repo without the signed-off-by footer the returned error message includes the line:
"The author is not a committer on the project"
This is clearly confusing some people as they aren't seeing past that warning to see the 'missing signed-off-by' which is what is actually blocking their change. To be fair not having permissions does seem like a more serious error, rather than a missing footer.
Can that line be suppressed in some way when people commit to the website repos?
