Add a `version` command for checking noirup's version installed

[Savio-Sou]

Problem

There is not currently a way to check the version of noirup installed on my machine.

Happy Case

Add a new noirup version command that returns the version of noirup I have installed, e.g.:

$ noirup version
noirup 0.1.4 (7dbe69c 2025-02-20)

Additional Context

Note that this behavior deviates from the Rust's similar rustup --version function, as noirup uses --version to select the version of Nargo to install.
