fix image build failure

Remove the platform parameter from Dockerfile

We should remove the fixed --platform=linux/amd64 from Dockefile to allow docker to choose right architecture when pulling the image.

If this change affects the github action, we should specify the platform parameter on github action task

Fix poetry version issue

When I try to build the image using docker compose build today, it failed due to a breaking change of poetry 2.0.0.

We need to put a constrain of 'poetry<2.0.0' for now.

docker compose build

> [django-socio-grpc server 1/1] RUN poetry install:
0.493
0.502 The Poetry configuration is invalid:
0.502   - project must contain ['name'] properties

Others are experiencing the same issue

This Poetry 2.0 has broken lots of things for us, a reminder to always put constraint on versions
