Consider changing --version to be more specific

[bhelx]

$ extism --version
extism version 1.0.0

I understand why it says this because the program itself is called extism but it might make more sense to override this and change it to something like extism-cli version 1.0.0. Because it could be confused that this is the lib version but they are in fact different things.

$  extism lib check
1.0.0
