ov init fails because Docker engine cannot be installed on Fedora 42

[obulat]

Description

Docker engine currently only supports Fedora 40/41, and does not support Fedora 42. This is why ov init is failing after the recent Fedora update in #5243.

There are also some other changes in dnf that make ov init fail.

Reproduction

1. Checkout the repository and run `ov init`. See the error: `Unknown argument "--add-repo" for command "config-manager".`
2. Replace the command in `docker/dev_env/Dockerfile` with `&& dnf -y config-manager addrepo --from-repofile=https://download.docker.com/linux/fedora/docker-ce.repo`
3. Run `ov init` and see another error:

Environment

• OS: MacOS with Fedora 42 in Docker (ov)

Additional context

To fix this issue, we need to:

• downgrade Fedora version to 41
• replace the config-manager command with && dnf -y config-manager addrepo --from-repofile=https://download.docker.com/linux/fedora/docker-ce.repo
• replace dnf with dnf5 as it's the supported version in Fedora 41
