Install using mise for those who prefer a package manager

Fwiw, install using mise works great:

```
❯ mise use -g github:tailscale/aperture-cli
github:tailscale/aperture-cli@0.0.8 extract aperture-cli_linux_amd64.tar.gz              ✔
mise ~/.config/mise/config.toml tools: github:tailscale/aperture-cli@0.0.8
```

And then `mise up` will manage versions.
