Fix test_version test

[puzzlewolf]

Hi :)

While packaging sarif-tools for NixOS, I noticed the test_version test fails because it expects 1.0.0 while the current version is 2.0.0. Here's an update for the test.

@balgillo Can you please have a look at this, it is a trivial change and will fix the broken tests.
