Improve error message when xz is not installed in the system

[JLarky]

What version?

No response

Which command?

curl -fsSL https://moonrepo.dev/install/proto.sh | bash

What happened?

proto error message:

$ curl -fsSL https://moonrepo.dev/install/proto.sh | bash

######################################################################## 100.0%
tar (child): xz: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now

compare that to error message Bun shows when you are missing unzip:

$ curl -fsSL https://bun.sh/install | bash
error: unzip is required to install bun (see: https://bun.sh/docs/installation#macos-and-linux)

No response

Operating system?

Linux

We use tar xf to unpack. I'll see if there's a way to detect what tar requires.

I think this will do it? moonrepo/moon#1387

[milesj]

Should error now.
