Issue with docker-compose version v2.17.2 can not parse networks twice

network is mentioned twice in ci-script/docker-compose.yaml. It is not necessary.

It can be removed

$:~/oai-mep$ docker compose -f ci-scripts/docker-compose.yaml up -d
yaml: unmarshal errors:
  line 43: mapping key "networks" already defined at line 35
  line 61: mapping key "networks" already defined at line 50
$:~/oai-mep$ docker compose -f ci-scripts/docker-compose.yaml up -d^C
$:~/oai-mep$ docker compose version
Docker Compose version v2.17.2
$:~/oai-mep$ grep -r kong-net^C
$:~/oai-mep$ docker compose versio^C
$:~/oai-mep$ grep -r kong-net
ci-scripts/docker-compose.yaml:      - kong-net
ci-scripts/docker-compose.yaml:      - kong-net

If we change it here we need to update the blueprint also.

Also we can mention in Readme that mongodb requires avx in cpu.
