fix: merge all apispecs correctly

[Panaetius]

there was a bug in the merging code, the notebooks spec file was saved in the repositories variable overwriting the repositories apispec, so this never ended up on our swagger page.

I rewrote the whole section to make is simpler and prevent this kind of error from happening again in the future.
