Installs vips-dev to the image so sharp can use it. The change also installs a few dependencies requires for sharp to build the C++ files required.

The version of alpine was upgraded from 18 to 19 because the minimum libvips required by sharp wasn't satisfied by alpine-18.

Finally, in addition to copying /apps, we are now also copying /lib and /usr/lib because libvips and some other dependencies are now needed. An alternative would be to list all the files needed but it would be tedious to maintain.

This change improves portability and security as pds is no longer depending on code built by a library but instead depends on the alpine package. An immediate benefit is that the alpine package doesn't use SSE4.2 instructions, allowing pds to run on older CPU like some Intel Atom processors.
