[bug#69587] [PATCH] doc: Add “Source Tree Structure” section.

[pelzflorian (Florian Pelz)]

Hi Ludo.

Good that I now have finally watched Josselin’s talk.

This section seems to be a good idea in general, but the examples are an
opinionated selection.  I believe the list should be small.  Listing
individual modules directly in ~/src/guix/guix directory is not useful
to newcomers or often self-explanatory.  gnu/installer, gnu/system,
gnu/build, gnu/machine is not useful to know.  po is better not talked
about, otherwise people edit translations directly in po, when they
should use Weblate.

What does core mean?  Perhaps (guix …) should be listed after (gnu …)
and defined as the Guix mechanisms that do not belong in gnu?  Not quite
sure either.

Remove duplicate “use”.
