[BUG] Compose 5.0.0 stopped respecting `BUILDKIT_PROGRESS`

[pjonsson]

Description

I just upgraded to Docker 29.1.3 from 29.1.2 on Ubuntu 24.04 and compose started to give fancy output when I have my BUILDKIT_PROGRESS set to plain. (It also messes up my terminal, but I see that has already been fixed.) Passing --progress plain as parameter to docker compose seems to still work.

Steps To Reproduce

With the official deb packages for Docker 29.1.3 with compose 5.0.0, run export BUILDKIT_PROGRESS=plain and then run docker compose -f docker-compose.yaml -f docker-compose.databaseservice.yaml up --build --wait -d.

Here's a start of my output:

[+] Building 1.0s (2/3)
