Podman-compose build doesn't work with Containerfile after v1.1.0

[omaxx]

Describe the bug
As per #167 podman-compose build should works with Dockerfile as well as with Containerfile

version 1.0.6 works
versions 1.1.0 and 1.2.0 give error:
OSError: Dockerfile not found in

To Reproduce
compose.yaml:

services:
  web:
    build: ./web

file Containerfile in web folder.

Expected behavior
with version 1.0.6:

❯ podman-compose build
podman-compose version: 1.0.6
['podman', '--version', '']
using podman version: 5.3.1
podman build -f ./web/Containerfile -t devops_web ./web
STEP 1/10: FROM registry.access.redhat.com/ubi9/ubi:9.5

Actual behavior
with versions 1.1.0 and 1.2.0:

❯ podman-compose build
