How to add fontconfig to builder-jammy-tiny

[lmm1990]

Hi, I have jhipster (spring boot) java project that use the Graphics2D stack of java to build a png image rendering a text inside it. I'm using the full stack paketobuildpacks/builder-jammy-tiny, i was searching a method to install into the final image this apt package but the only thing that i found is to create a custom stack with this. There is no way to add an additional build like the apt-buildpackage or some environment that add this specific package to the ubuntu run image?
