No known_valid_packs.json present, resource pack not working

I've been trying to install several crafting tweaks from bedrocktweaks.
Even after following all the steps specified in the docs, the pack is not installed properly and does not work.
From what I've seen in other tutorials, there should be a known_valid_packs.json in the data directory, that gets updated whenever a new directory is created within /data/resource_packs or /data/behavior_packs. However, no such file exists.

Minecraft Bedrock version: 1.21.31.04
docker-minecraft-bedrock-server version: latest (28e90626f0e4)
Resource pack: [better crafting.zip](https://github.com/user-attachments/files/17227714/better.crafting.zip)

Start by comparing the documented pack-install steps with the data directory, especially the expected relationship between known_valid_packs.json, resource_packs, and behavior_packs. Reproduce the setup with better crafting.zip on the stated Bedrock version; done means the expected file is present and the resource pack works.
