Fix Get-TfsGitItem (#251)

* Fix Commit version assignment in GetGitItem

Updated the version assignment in the GetGitItem class to use the Commit property instead of converting the item to a string. This change ensures that the correct commit version is retrieved when using the "Get by commit SHA" parameter set.

* Update release notes

* Change the Commit property to string
