fix CI speed

Describe your changes

This PR speeds up the CI, it was slowing down a lot because of a problem in ploomber-core

you can see it here:

before: https://github.com/ploomber/jupysql/actions/runs/5546740202/jobs/10127439854
after: https://github.com/ploomber/jupysql/actions/runs/5558949460/jobs/10154574710

i.e., Python 3.11 ubuntu went from 25mins to 6.5 mins! (on windows the performance increased even more)

(opened ploomber/core#70 to investigate the root cause)

Do you think it would help if we document these CI fix changes in the developer docs? There was one related to upload docs build cache to S3, and this one also. Might be easy for reference @edublancas

for this one, it'll be better to just fix the core problem, that's why I opened ploomber/core#70 this is a temp fix
