[dmnxprss]

Describe the bug

When building services, pdm tries to install packages but fails at nltk.

No candidate is found for nltk that matches the environment or hashes

On researching, it seems that ntlk 3.8.2 was removed link and replaced with 3.9b1

To reproduce

run VERSION=dev docker compose -f docker-compose.build.yaml build backend

Expected behavior

Clean build of image
