Quadlet Label Value Truncation Due to Missing Quotes

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description
When a Quadlet file is written, the "Label=" line values are not quoted. This causes issues if there are special or escape characters in the value.

For example, the following quadlet file is currently generated.

[Container]
ContainerName=testapp
...
Label=traefik.enable=True
Label=traefik.http.routers.testapp.rule=( Host(`test.com`) && PathPrefix(`/path`) )

When it should be (notice the extra quotes around Label=.

[Container]
ContainerName=testapp
...
Label=traefik.enable="True"
Label=traefik.http.routers.testapp.rule="( Host(`test.com`) && PathPrefix(`/path`) )"

Steps to reproduce the issue:

- containers.podman.podman_container:
     name: testapp
     state: quadlet
     quadlet_filename: container-testapp
     quadlet_options:
       - "AutoUpdate=registry"
       - "Pull=always"
       - |
         [Install]
         WantedBy=default.target
    network:
      - podman
    image: docker.io/containous/whoami
    labels:
      traefik.enable: true
      traefik.http.routers.testapp.rule: "( Host(`test.com`) && PathPrefix(`/path`) )"

Describe the results you received:

$ podman inspect testapp
...
      "Labels": {
        "traefik.http.routers.testapp.rule": "(",
      }

Describe the results you expected:

$ podman inspect testapp
...
      "Labels": {
        "traefik.http.routers.testapp.rule": "( Host(`test.com`) && PathPrefix(`/path`) )",
      }

Double quoting the label within containers.podman.podmain_container is a workaround.

...
- containers.podman.podman_container:
    ...
    labels:
      traefik.http.routers.testapp.rule: "\"( Host(`test.com`) && PathPrefix(`/path`)\""
...

Version of the containers.podman collection:
Either git commit if installed from git: git show --summary
Or version from ansible-galaxy if installed from galaxy: ansible-galaxy collection list | grep containers.podman

1.15.4

Output of ansible --version:

ansible [core 2.15.10]

Output of podman version:

$ podman --version
podman version 4.9.4-rhel

Package info (e.g. output of rpm -q podman or apt list podman):

$ rpm -q podman
podman-4.9.4-4.module+el8.10.0+21995+81e8507c.x86_64

I think this workaround might be actually a legit way to do quotes inside, anyway we'll need to escape quotes in the label value if they exist.
