[BUG] Compose STILL does not observe the BUILDKIT_PROGRESS environement variable

Description

Buildkit provides ways of configure non-pretty (plain) build progress output through either a runtime flag (--progress=plain) or via an environment variable (BUILDKIT_PROGRESS=plain). Compose currently ignores the environment variable.

Support for the environment variable was supposed to be added in #12458 (released in Compose v2.33.0). This didn't work, and was then supposed to be fixed in #12894 (released in Compose v2.37.0). This again does not seem to work.

Steps To Reproduce

Run a Compose stack using the BUILDKIT_PROGRESS=plain environment variable:
```
BUILDKIT_PROGRESS=plain docker compose up
```
Expected output: plaintext build and stack output, equivalent to running Compose with the --progress=plain flag.
Actual output: pretty output with paging, colors, and multiple output streams writing to the terminal at the same time.
