[PATCH 3/4] piem-inboxes: Clarify that :coderepo points to a working tree

[Kyle Meyer <kyle@kyleam.com>]

The properties of piem-inboxes align with public-inbox-config names to
keep things consistent, which is especially important given the
upcoming support of reading inboxes from public-inbox's configuration.
However, :coderepo, which needs to point to a working tree, doesn't
nicely match publicinbox.$inbox.coderepo, which points to another
section that in turn must point to a .git directory.

I'm still undecided on whether using a different name (e.g.,
:code-working-tree) would be clearer, but at least document the
difference to hopefully avoid some confusion.
