Add name to DevContainer compose file

[duduribeiro]

Motivation / Background

Currently when you generate a project the compose.yaml generated file does not include the top-level name property. Not having this top-level name property makes all containers / volumes started by devcontainer to be prepended with the folder name, which is devcontainer in the case of the .devcontainer/compose.yml` file.

docker compose -f .devcontainer/compose.yaml up -d

[+] Running 4/4
 ✔ Container devcontainer-postgres-1   Started                                                                                                   0.0s
 ✔ Container devcontainer-selenium-1   Started                                                                                                   0.0s
 ✔ Container devcontainer-rails-app-1  Started

This is ok if you run only one project with devcontainer but starts to get problem if you run multiple projects. If you have one project that runs on postgresql 15 and a new one that runs on postgresql 16 it will fail to boot the postgresql container because both devcontainers is using the same volume: devcontainer_postgres-data.

PostgreSQL Database directory appears to contain a database; Skipping initialization

2024-05-11 04:15:34.246 UTC [1] FATAL:  database files are incompatible with server
2024-05-11 04:15:34.246 UTC [1] DETAIL:  The data directory was initialized by PostgreSQL version 15, which is not compatible with this version 16.1 (Debian 16.1-1.pgdg120+1).

Detail

This commit fixes this by setting the top-lavel name property with the project name, which will make the containers and volumes to be prepended with the project name and not with devcontainer.

With the top name property:

Devcontainer smoke test container is failing because devcontainers/ci is using the old compose version that is deprecated since jul 23 https://docs.docker.com/compose/migrate/

checking if we can run the CI with the newer compose version

[duduribeiro]

removed the old and deprecated docker-compose 1.29.1 (from may 10, 2021), so it uses the compose v2 https://docs.docker.com/compose/migrate/
