Change WORKDIR from / to /usr/src/app

[waterkip]

What changed is that in bookworm the lib dir has become a symlink to /usr/lib. This prevents COPY . . to copy over our lib dir to the layer.

LGTM, thanks @waterkip ! 🙏

Can we add a test in https://github.com/Perl/docker-perl/blob/master/.github/workflows/build-image.yml based on what we've observed (so on the off chance we revert WORKDIR or some other change happens, we can can catch this issue later?)

[waterkip]

Added the test.

It might be considered a breaking change. For example, if someone did COPY foo . and later on does RUN /foo it will stop working.

LGTM! +1 thanks for this - as for the breaking change, I think Debian broke us first joy_cat we'll just make an update on our doc and move forward rocket

Haha, ok ok :)
