Using finalAttrs.src for all derivations makes it
possible to override the source using overrideAttrs
without having to reimplement part of the logic
within the immich package.
Using finalAttrs.passthru.web in the installPhase additionally
makes it possible to override only the web derivation.
Overriding immich in passthru.machine-learning makes
sure that the exposed immich-machine-learning also
uses the updated src.
