[Bug]: Ansible feature always installs the latest version

[koralowiec]

Feature id and version

ghcr.io/devcontainers-extra/features/ansible:2.0.17

Devcontainer base Image

mcr.microsoft.com/devcontainers/base:bookworm

What happened?

Ansible feature doesn't install ansible-core in the specified version

devcontainer.json:

{
    "name": "Debian",
    "image": "mcr.microsoft.com/devcontainers/base:bookworm",
    "features": {
        "ghcr.io/devcontainers-extra/features/ansible:2.0.17": {
            "version": "2.16.11"
        }
    }
}

test_version_selection scenario doesn't catch it when the tests are run - The following check doesn't fail even though the version is not matched:

check "ansible --version | grep 'core 2.13.0'" ansible --version | grep 'core 2.13.0'

It fails when I change it to this:

check "ansible --version | grep 'core 2.13.0'" bash -c "ansible --version | grep 'core 2.13.0'"

Relevant log output

No response

check "ansible --version | grep 'core 2.13.0'" ansible --version | grep 'core 2.13.0'

The "false positive" caused by the fact that the output of check function is piped to the grep 'core 2.13.0'. And the output contains the "label" that is passed as the 1st argument ("ansible --version | grep 'core 2.13.0'"). As the result the grep is always successful - core 2.13.0 is always present in the check's output
