[PATCH 1/5] doc: config: document --[no-]show-names

From: Kristoffer Haugsbakk <redacted>

These options were introduced in 4e513890008 (builtin/config:
introduce "get" subcommand, 2024-05-06) but not documented here.
Use the description from the source code.

Document this option and the negated form according to the current
convention.[1]

`--show-names` is also the default when `--get-regexp` is given.  But
don’t mention it here since all the deprecated modes are quarantined in
the “Deprecated Modes” section.

    >The default is `--no-show-names` unless `--url` is given and there are
    > no subsections in _<name>_.
