Add kurtosis cli as a nix package

[corduroybera]

Background & motivation

Since kurtosis already supports nix images, would love to also see kurtosis cli as a nix tool. Currently, I'm using brew to install it but I much prefer using nix when possible.

Desired behaviour

Install kurtosis cli by adding "kurtosis" to my nix pkg machine configuration
