[PATCH] Documentation/config.txt: fix typo in core.alternateRefsCommand

In [1] Git learned about 'core.alternateRefsCommand', and with it, the
accompanying documentation. However, this documentation included a typo
involving the verb tense of "produced".

Match the tense of the surrounding bits by correcting this typo.

Note: this can be applied as a fixup to the commit [1] mentioned above.
I'm sending it as a separate series, since the patches have already
landed on 'next'.

They were originally introduced in:

  7451b4872a0fd66d84cbe492fdfe7a9a8e81eab7.1539021825.git.me@ttaylorr.com

I think that these will ultimately conflict with Duy's patches to move
Documentation/config.txt out to separate files. It seems, however, that
he may re-roll the series beforehand, so I can either:

  1. Resend this once he has landed his changes, or,

  2. He can re-roll with this version of Documentation/config.txt.
