        Gets repositories from Azure DevOps
    .Description
        Gets the repositories from Azure DevOps.

        By default, this will return the project's git repositories.

        Azure DevOps repositories can have more than one type of SourceProvider.

        To list the Source Providers, use -SourceProvider

        We can get repositories for a given -ProviderName
    .Example
        Get-ADORepository -Organization StartAutomating -Project PSDevOps
