wekan: Latest MongoDB images require AVX instructions - Debian VMs fail to run

Issue

After the latest update the mongodb image keeps restarting complaining about AVX instructions.

Problem description

After the latest update (today) the wekandb container is continously restarting with the following error message:

$ docker compose logs
wekan-db   | WARNING: MongoDB 5.0+ requires a CPU with AVX support, and your current system does not appear to have that!
wekan-db   |   see https://jira.mongodb.org/browse/SERVER-54407
wekan-db   |   see also https://www.mongodb.com/community/forums/t/mongodb-5-0-cpu-intel-g4650-compatibility/116610/2
wekan-db   |   see also https://github.com/docker-library/mongo/issues/485#issuecomment-891991814

Reproduction Steps

• Download / copypaste the docker-compose.yml in a Debian Buster virtual machine (at least this is my setup)
• Run the compose stack (I have compose v2, tho it should not matter)
• Fail

Logs

The wekan image is working but cannot connect to the database, the wekandb logs are provided above.

Proposed solution

Either:

• Document this thing somewhere where stupid users like me who just run apt update && apt upgrade -y can reference something and know what’s actually going on before digging through GitHub issues and Jira tickets and all that good stuff
• Default to MongoDB 4.x something (or at least for now), which is what I’m gonna do right now
• Both the above 🤷🏻
