Why does ubuntu-latest use docker-compose V1 and not V2?

[metinc]

When I use the command docker-compose -v I get docker-compose version 1.29.2, build 5becea4c. How can I switch to V2?

According to the Readme has both V1 and V2. But how do I use V2?

Seems like I just had to use docker compose and not docker-compose.
