Update docker-compose.yaml

Set the mongo version to 4.4 to make it work on ubuntu20.04 and 18.04.

It works.

@nicklhj
Even though it works... Why do you want such an old version of Mongo??? The compatibility of this has nothing to do with the operating system, but whether the processor supports avx instructions for mongo versions >= 5

Well, I think the perfect solution would be to use different MongoDB versions depending on the processor support to avx instructions. Still though, I've made no research to find out if it's possible to do or how to implement it.

Than you for the contribution @nicklhj, and @ojpojao for pointing the cpu issue with MongoDB. Found this link of people going through the same problem: https://stackoverflow.com/questions/70818543/mongo-db-deployment-not-working-in-kubernetes-because-processor-doesnt-have-avx . There could some kind of shell script at Oktopus to check cpu support to avx: https://stackoverflow.com/questions/37480071/how-to-tell-if-a-linux-machine-supports-avx-avx2-instructions and based on the return set the mongodb version.
