[Feature]: Use compose project name as workspace name

Problem or motivation

I want to use .devcontainer.json together with docker compose files that already specify a local development environment.

Currently devsy doesn't match the workspace name with the configured docker compose project name via the .env file inside dockerfiles.

The the projects layout looks like:

- .devcontainer.json
- dockerfiles
|-- .env
|-- docker-compose.yml
|-- docker-compose.dev.yml

The contents of .devcontainer.json is

{
	"name": "foobar",
	"dockerComposeFile": ["dockerfiles/docker-compose.yml", "dockerfiles/docker-compose.dev.yml"],
	"service": "backend"
}

The dockerfiles/.env contains COMPOSE_PROJECT_NAME=foobar.

When executing devsy workspace up . using docker provider, it ignores both name and COMPOSE_PROJECT_NAME and creates the container using a random id as project name.

This also applies even when adding this to any docker-compose.yml

name:  foobar
services: 
  frontend:
    ...
  backend:
    ...

It only works when exporting COMPOSE_PROJECT_NAME to the current shell session.
Tested on fedora using v1.15.0

Proposed solution

1. Respect name inside .devcontainer.json for workspace name when using compose project.
2. Override with name property of merged dockerComposeFile for workspace name
3. Override with config of .env files at following locations: .devcontainer/.env, folder of specified dockerComposeFiles to override via COMPOSE_PROJECT_NAME
4. (already implemented) Current sessions' COMPOSE_PROJECT_NAME should override all configs

Alternatives considered

No response

Area

Dev containers, CLI

Acceptance criteria

Not spawning a seperate compose project when using devsy workspace up ., when a project is already running and configured via docker compose.
