Add Fedora 43.

Blindly copy the fedora 42 Dockerfile for fedora 43, just change the version number.

- Description for the changelog

Add Fedora 43 packages

[vvoland]

LGTM overall, but I think Fedora 43 isn't "out" yet so perhaps we should still give it some time before having official stable packages?

[Romain-Geissler-1A]

In the past we have merged Fedora N support before its actual release (usually around the beta phase where things are stabilizing). If you mark this "not stable" then on the D day of the Fedora release packages won't be available (even after merging this, no new docker/containerd package will be made available until the next containerd/docker actual release, which on occasion can take some time).

I try to proactively send pull requests like these since couple of years since I regularly hit the issue that docker (I am especially interested in the docker client) was not installable from the quay.io/fedora/fedora OCI image more or less every 6 months and that created issues in my own CIs.

Thanks! I was missing the bit about Fedora 43 being released as beta this week. In this case I think it's good to have it already.

@Romain-Geissler-1A do you have a moment to rebase this one? Jenkinsfile is gone now.

Otherwise I can rebase this one and get it in.

[vvoland]

I went ahead and rebased this one, hope you don't mind! 🙈

[Romain-Geissler-1A]

Thanks for the rebase, I was off yesterday.

So, don't we need docker/containerd-packaging#427 as well ? Because the resulting docker rpm packages won't be installable without the required containerd dependency.

[vvoland]

No. Sorry for the confusion. We're in the middle of reworking the release pipeline.

Currently only docker/docker-ce-packaging and docker/packaging (containerd only) are used.

In the nearest future (after we get v29 out) the docker/packaging will be the source for building all packages.
