test(access): pin the ReadSecurityError category of Get-NTFSAccess after a failed ownership retry

Get-NTFSAccess writes ReadSecurityError with category WriteError when a
read succeeds only after the cmdlet takes ownership and the restored
owner is irrelevant to that path; Get-NTFSAudit, Get-NTFSEffectiveAccess,
Get-NTFSInheritance, and Get-NTFSSecurityDescriptor already report the
same failure the same way, so this is the module's convention, unlike
Get-NTFSOrphanedAccess, whose own category for the same failure is
ReadError. No script could notice: the behavior does not change. A
characterization test in Tests\ParameterSets.Access.Tests.ps1, next to
the orphaned-access test that already pins the ReadError side of the
same convention, is green at once and runs in all four configurations.
