[PATCH 2/3] meson: print docs backend as part of the summary

From: Patrick Steinhardt <ps@pks.im>

Message-ID: <20250911-b4-pks-meson-docs-target-v1-2-a92c666ecef9@pks.im>
In-Reply-To: <20250911-b4-pks-meson-docs-target-v1-0-a92c666ecef9@pks.im>

Our documentation can be built with either Asciidoc or Asciidoctor as backend. When Meson is configured to build documentation, then it will automatically detect which of these tools is available and use them. It's not obvious to the user though which of these backends is used unless the user explicitly asks for one backend via `-Ddocs_backend=`.

Improve the status quo by printing the docs backend as part of the "backends" summary.
