Create two new ECS containers for zksync remix plugin devnet backend (Dev and Prod)

[stranger80]

We need to extend the devnet setup ECS task set for zkSync Remix plugin (both Dev and Prod instances).
Currently we have a single task/container for a devnet ECS service (screenshot from Prod below):

We need this extended to 3 ECS containers in each environment, to implement a following setup (as specified in the docker compose yaml): https://github.com/matter-labs/local-setup/blob/main/docker-compose.yml

Pleae implement the automated deployment to this service in:

• Dev: https://github.com/NethermindEth/zksync-remix-plugin/blob/develop/.github/workflows/devnet-deploy.yml
• Prod: https://github.com/NethermindEth/zksync-remix-plugin/blob/develop/.github/workflows/devnet-prod-deploy.yml
