DL3041 warnings when package name is not hyphen-separated from version

Expected behavior

Preferably there would be no DL3041 warnings when a package is dnf install 'd that is not hyphen-separated from its pinned version, especially when such packages are unavailable.

Example: python-3.11 does not cause a DL3041 warning, but in not available; python3.11 is available, but causes warnings.

Actual behavior

DL3041 warning: Specify version with `dnf install -y <package>-<version>`.

Steps to reproduce the behavior

Output of hadolint --version or
docker run --rm hadolint/hadolint hadolint --version or
docker run --rm ghcr.io/hadolint/hadolint hadolint --version:

$ hadolint --version
Haskell Dockerfile Linter 2.12.0

Dockerfile

ARG python_version=3.11
RUN microdnf install -y python${python_version} \
                        python${python_version}-pip \
