Backend instructions should explain how to add add-ons

Plone Documentation versions affected

• [ ] 5.x
• [X] 6.x

Description

The plone-backend container documentation does not explain how to add add-ons except through ADDONS variable, which is explicitly said not to be for production.

Perhaps we should explain this in the docs too. Here is how I do it:

COPY dist/ dist/

RUN echo Installing dist/*.tar.gz >&2 && \
    ./bin/pip -q install dist/*.tar.gz && \
    ./bin/pip check && \
    echo ===Packages installed in the container image=== >&2 && \
    ./bin/pip freeze && \
    echo =/=Packages installed in the container image=/= >&2
