Use psycopg2 instead of psycopg2-binary.

[Ayrx]

This PR changes DefectDojo to use the psycopg2 package instead of psycopg2-binary.

This fixes a problem with running DefectDojo on aarch64 machines, with the main motivation here being able to do dev work on an Apple Silicon Macbook.

The psycopg2 package also recommends build from source instead of relying on the binary package.

The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.

There was some talk about moving to psycopg3 recently. That may be the better approach here

[mtesauro]

I agree with @Maffooch - if we're going to change how we handle that dependency, might as well upgrade to psycopg3

[Ayrx]

I'm not familiar enough with the DefectDojo codebase to make that change, since I believe the APIs aren't compatible, so someone else will have to take that on. :)

@Ayrx thank you for your PR, we're going to work internally on going to psycops3, so I think adding the binary is moving in the wrong direction.

It occured to me that you will have the same issue with psyocpg3. The recommended installation method for production sites is the local installation method which still requires libpq-dev.

@Ayrx so? are you modifying your PR to switch to psyocpg3 or we abandon this PR?

psycopg3 is not ready for Django yet, so this is a good step in the right direction :)

Thanks @Maffooch for doing the research on this 👍
