Remove Fedora 37 & add Fedora 39

[nicrowe00]

Removing Fedora 37 from the CI as it's now EOL and adding Fedora 39.

Oh. The CI config is trying to use dnf on alpine.

I think we can drop these lines now:

          if [[ ${{ matrix.dotnet_version }} == "8.0" ]]; then
            dnf install -y dnf-plugins-core
            if [[ ${{ matrix.container_image }} == *ubi8* ]] ; then
              dnf copr enable -y @dotnet-sig/dotnet-preview rhel-8-$(uname -m)
            else
              dnf copr enable -y @dotnet-sig/dotnet-preview
            fi
          fi

That was trying to use the https://copr.fedorainfracloud.org/coprs/g/dotnet-sig/dotnet-preview/ repo to install .NET 8, but .NET 8 should be available everywhere now.

@ayakael hey, do you know how we can install .NET 8 on alpine:edge? Based on https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/49831/diffs#c3a9fd6134014af4ee84828b0a9166e7f40f9d85, I was expecting the following to work, but it doesn't:

$ podman run -it alpine:edge

All errors are in tools-in-path and managed-symbols-are-available, both of which are known issues. I am merging this PR.

@omajid Sorry for not having come back to you, december was a busy month. .NET 8 is now merged on edge. I've re-enabled CI via #330

[omajid]

No worries, and thanks for that PR!
