Exclude disabled repos by default

[l-a-u-r-e-n-c-e]

This fixes 404 responses when attempting to make requests to disabled repos.

Description

I added a new switch param as I figured it was best not to always exclude disabled repos from responses. However, the default is to exclude them as I didn't want to affect the rest of the code. I did check to see if AzDO supports OData filters but it doesn't look like that's the case so we have to filter it after the response is received.

Motivation and Context

Currently, if you run the tool on a Project with a disabled repo then it throws an exception.

How Has This Been Tested?

I ran the Get-AzDevOpsRepos cmdlet after making the change and observed that the disabled repo in my project was no longer in the returned array. I ran the tests for DevOps.Repos.Tests against my project and got the following:
