Update Docker Compose to v2.38.2+

[janbrasna]

Description

#12649 made a breaking update that enabled COMPOSE_BAKE by default. That also had followup fixes released that are necessary for successful runs.

The current image deployed ships a version that can leave the build process hanging indefinitely. docker/compose#12998

Doesn't reproduce since v2.38.1 or v2.38.2 — please update ASAP

Hi @janbrasna, Thank you for bringing this issue to our attention. We will look into this issue and will update you after investigation.

Using pinned versions of explicit docker/setup-compose-action@v1 I've confirmed v2.37.3 failing, and v2.38.2 passing on the same SHA.

(docker/compose#12998 (comment))

I'm picking v2.38.2 as the most conservative of the versions to have this regression fixed, and submitting a PR right away for further review to get this moving ASAP.
