Update docker-compose.yml (#7962)

If the name field is not specified, Docker Compose will default to using
`docker` as the project name. This may cause conflicts with other
default projects, leading to unintended operations when executing
`docker compose` commands.

### What problem does this PR solve?

When executing Docker Compose commands, interference occurs between
multiple default projects, leading to operational chaos.​
