Update Nix Package for Run as Part of Release Cycle

[TekWizely]

Just a reminder to incorporate updating Run's Nix Package as part of our release cycle.

From discussion here:

• run: init at 0.7.0 NixOS/nixpkgs#77081 (comment)

To contribute to nixpkgs (update a package for instance), we submit PR, such as the current one. You could find more details in the nixpkgs manual: https://nixos.org/manual/nixpkgs/stable/#submitting-changes-making-patches

run: 0.7.2 -> 0.9.1
