docker-compose: Changes group type from int to str

[herostrat]

With the docker-compose file I got the following error:

$ docker-compose up
3 error(s) decoding:

• 'group_add[0]' expected type 'string', got unconvertible type 'int', value: '109'
• 'group_add[1]' expected type 'string', got unconvertible type 'int', value: '44'
• 'group_add[2]' expected type 'string', got unconvertible type 'int', value: '46'

This commit changes the type to string to fix this issue.

$ docker-compose --version
Docker Compose version 2.3.3

I have seen this as well, what platform are you on? I'm on macOS, curious why it works on some systems and not on others.

This is just a change in the transition from V1 to V2 docker compose. I switched to V2 and I see the same error.
