[FEATURE REQUEST] Is MongoDB backward compatible with version 4.4? Some device CPUs do not support the AVX instruction set

[yll14]

Why this feature?

MongoDB v4.4 is the last version that does not require the AVX instruction set Some device CPUs do not support the AVX instruction set MongoDB 5.0 mandates the AVX instruction set, which is not friendly to some users

Suggested Solution

Backward support for MongoDB to version 4.4 has enabled users whose CPUs do not support the AVX instruction set to use OpenIM normally

Additional Information

The current docker-compose init script uses mongosh, which is only available in MongoDB 5.0+ images. MongoDB 4.4 uses the legacy mongo shell.

To use MongoDB 4.4, two changes are needed:

1. In .env, change:
   MONGO_IMAGE=mongo:4.4

2. In docker-compose.yaml, replace mongosh with mongo in the mongo service init script (lines 12 and 16).

OpenIM server/chat applications use the standard MongoDB Go driver and have no version restriction. This adjustment should work.
