make the ojp-server docker image leaner

[matheusandre1]

Closes #49 , This reduces it, but is that all there is to it?

@matheusandre1 have you run the integration tests against the new image? Would be great if you could run all integration tests against the old image and then against the new one to compare.

@matheusandre1 have you run the integration tests against the docker image? Currently, in the CI workflow we don't run tests against the docker image, we run OJP Server as an executable JAR. That is why I am insisting on testing it locally.

[matheusandre1]

Yes, I rotated and built an image on top.

@matheusandre1 , the integration tests I'm referring to are the ones that are in ojp-jdbc and run against the real databases. there's a video explaining it here: https://youtu.be/KFR-DGmc2A0?si=wxZe-PcK5QP0wjoM

I'll check it out, thanks for reminding me about that, I believe the CI is costly for you.

@matheusandre1 it's not about the cost, it is that the CI does not use docker images, it runs an executable JAR only at the moment.

I'll do that tonight, I'm having trouble testing it, I'm using ACT and it's gotten worse lol
