Environment should not be set in build context

[emersion]

Describe the bug
Values in environment in docker-compose.yaml should not be set during container build, they should only be set during runtime.

To Reproduce

Dockerfile:

FROM alpine:latest
RUN ["env"]

docker-compose.yaml:

services:
  test:
    build:
      context: .
    command: ["env"]
    environment:
      FOO: bar

Expected behavior
FOO is not set when running podman-compose build, FOO is set when running podman-compose up.

Actual behavior
FOO is set in both cases.

Output

$ podman-compose version
podman-compose version 1.1.0
podman version 5.1.1

$ podman-compose build
STEP 1/3: FROM alpine:latest
STEP 2/3: ENV "FOO"="bar"

STEP 3/3: RUN ["env"]

• podman compose version: 1.1.0

There's no response from https://github.com/hedayat on the PR #729, so I think what makes sense is to revert this.
