bvn13/kat repository not available for Fedora 38

[rmarting]

Following the instructions to install the tool in a Fedora 38 laptop, an error happens with the following message:

Repository 'fedora-38-x86_64' does not exist in project 'bvn13/kcat'.
Available repositories: 'fedora-37-x86_64', 'mageia-8-x86_64', 'fedora-36-x86_64', 'centos-stream-9-x86_64', 'epel-9-x86_64', 'fedora-35-x86_64'

The bvn13/kat repository is not available for Fedora 38, only for previous versions.

It is possible to enable a previous repository to use it, and install it (with some errors and warnings in the output). It could be better to have a repository for Fedora 38, instead of to use a older one.

Steps to reproduce it

1. Enable the repository, this process fails with the error:

❯ sudo dnf copr enable bvn13/kcat
Enabling a Copr repository. Please note that this repository is not part
of the main distribution, and quality may vary.

The Fedora Project does not exercise any power over the contents of
this repository beyond the rules outlined in the Copr FAQ at
<https://docs.pagure.org/copr.copr/user_documentation.html#what-i-can-build-in-copr>,
and packages are not held to any quality or security level.

Please do not file bug reports about these packages in Fedora
Bugzilla. In case of problems, contact the owner of this repository.

Error: It wasn't possible to enable this project.
Repository 'fedora-38-x86_64' does not exist in project 'bvn13/kcat'.
Available repositories: 'fedora-37-x86_64', 'mageia-8-x86_64', 'fedora-36-x86_64', 'centos-stream-9-x86_64', 'epel-9-x86_64', 'fedora-35-x86_64'

If you want to enable a non-default repository, use the following command:
  'dnf copr enable bvn13/kcat <repository>'
But note that the installed repo file will likely need a manual modification.

2. Enable the repository for a previous Fedora distro, e.g. Fedora 37:

❯ sudo dnf copr enable bvn13/kcat fedora-37-x86_64

3. Install the package, however, new errors are showed in the output:

❯ sudo dnf install kafkacat
