Document visidata Package on Fedora

[almereyda]

Currently the website on https://www.visidata.org/install/ does not state availability of visidata in Fedora.

When running sudo dnf install visidata on a recent release, it offers an installation (together with a bunch of dependencies) to system python. The binary will then be available.

Thank you, I've made a PR to add Fedora to the list at the repo for the visidata.org website. I don't use Fedora, so please let me know if the link to the package URL looks appropriate to you: https://packages.fedoraproject.org/pkgs/visidata/visidata/
