Missing contributors from Get-GitHubRepositoryContributor

[Liturgist]

Issue Details

The PowerShell GitHub project page reports that is has 424 contributors. However, using Get-GitHubRepositoryContibutor reports only 378 contributors. Using -IncludeAnonymousContributors reports 467.

I also have a GitHub Enterprise repo which has four (4) contributors, but Get-GitHubRepositoryContributor reports only two (2) contributors.

Steps to reproduce the issue

View the "Contributors" on https://github.com/PowerShell/PowerShell

PS C:\> (Get-GitHubRepositoryContributor -OwnerName 'PowerShell' -RepositoryName 'PowerShell').Count
378

PS C:\> (Get-GitHubRepositoryContributor -OwnerName 'PowerShell' -RepositoryName 'PowerShell' -IncludeAnonymousContributors).Count         
467
