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

**Describe the bug**
As per https://github.com/containers/podman-compose/issues/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
