Build nightly with patched source build #94
Description
As a followup of #93, it might be a good idea to build nightly builds with a source build of nightly libzim source, instead of nightly libzim WASM precompiled binaries, until we can fix the issue in libzim at source, or else patch the kiwix-build compile of the binaries.
This isn't urgent, but as I don't want to make an official release with on-the-fly patched search.cpp and suggest.cpp, it would be strange to have the nightlies falling behind the protoype in terms of support for multiple languages.
