help: fix a py3 error interpolating Set into b'%s'

I can't reproduce it, but a coworker hit this with `hg help -v` with 6.2.3:

    ...
      File "mercurial\help.pyc", line 865, in helplist
    TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'set'

I can confirm that the original expression fails in `hg debugshell`, and the new
one works.  The second instance was found by searching for "%s", but PyCharm
detects a lot of variables as Any type, so I have no idea if there are other
lurking problems.
