Handle complex azureauth output

[muiriswoulfe]

azureauth on some devices is returning a complex output, in the format below. This change ensures that ado-npm-auth will work with both this output and the one previously supported.

2 tests have been added to validate this.

By the way, the linter automatically applied some styling fixes for the test file, which I left in place. I can revert these if desired.

0.8.5.0

So the complex output is just extra empty lines around the actual version info?

Empty lines and lines beginning with '>'. See the example in my PR description.

Ah sorry I misunderstood that as being what you ran to generate the output. I think we might need to use the --silent flag on the npm exec command. Would you be able to try something like that on your system and see if it works to suppress that noisy output

I tried npm exec --silent --yes azureauth -- --version and that works. That's a better solution for sure, so I'm happy to update my PR to that fix.

By the way, I found that all calls to azureauth can have this issue so the change will need to be made throughout to those calls.
