🩹 Use debian base image to allow using odiff as diffing backend (#297)

• 👌 Use debian base image to allow usage of odiff

Odiff isn't ABI compatible with musl-libc (alpine) and thus causes crashes when called. Where as debian uses gnu-libc which is compatible with the odiff binaries.

• 🧹 Remove deprecated docker compose file version

Ref.: https://github.com/compose-spec/compose-spec/blob/main/spec.md#version-and-name-top-level-elements

• 🤔 Also use debian base image for migrations? (consistency)

Using the same base image for migration and the API might reduce debugging afford for bugs related to prisma alpine/debian differences (i.e. binaryTargets)

• 🩹🚇 Use docker compose v2 CLI call in workflow

This fixes the error: "docker-compose: command not found"
