podman-compose build does not support environment type secrets

[pikkle-rick]

Describe the bug
When using podman-compose build it errors out on having any secrets defines as environment:. This is supported in the compose spec

To Reproduce
Steps to reproduce the behavior:

1. From the root of a repo create the following:

• test-image/Dockerfile
• docker-compose.yml

2. Contents of Dockerfile:

FROM redhat/ubi9:latest

RUN --mount=type=secret,id=proxy_username,target=/etc/yum/vars/proxy_username \
    --mount=type=secret,id=proxy_token,target=/etc/yum/vars/proxy_token \
    microdnf upgrade -y --nodocs && \
    microdnf install -y --nodocs tar gzip

3. Contents of docker-compose.yml

version: "3.8"
services:
  test-image:
    build:
      dockerfile: ./test-image/Dockerfile
      secrets:
        - proxy_username
        - proxy_api_token
    image: ${IMAGE_PATH:-test-image}:${IMAGE_TAG:-latest}
secrets:
  proxy_api_token:
    environment: PROXY_REGISTRY_API_TOKEN
  proxy_username:
    environment: PROXY_REGISTRY_USERNAME

4. Set the variables in your environment

export PROXY_REGISTRY_USERNAME="test-user"
export PROXY_REGISTRY_API_TOKEN="test-token"

5. Run podman-compose build
   podman-compose build test-image

Expected behavior
podman-compose should have access to the environment variables set on the host/container it is running in and pass them along.

Actual behavior
podman-compose fails at parsing the yaml file.

Output

$ podman-compose -v
podman-compose version 1.2.0
podman version 4.9.4-rhel

$ podman-compose build test-image
