docs(access): say that a local standard user still gets "Access is denied" for a domain user account

Get-NTFSEffectiveAccess already falls back to the local authorization
manager for a name of this computer when the remote one refuses the
caller, which covers every account except a user account of the domain:
Windows still answers "Access is denied" for that one case, because the
local manager has no domain credentials to resolve it. The cmdlet
already writes this as a non-terminating GetEffectiveAccessError and
returns no result for the item; nothing in the behavior changes.

Docs\Cmdlets\Get-NTFSEffectiveAccess.md gets one more NOTES paragraph,
in the style of the neighboring "Before 5.0.0..." paragraphs, saying so
and naming the accounts that still get a result (accounts of this
computer, and domain groups such as Everyone or Domain Users). Evidence:
Tests\Lab\Acceptance-2026-10-10-os-matrix.md, "The probe", row "Local
standard user". No code change; Tests\Help.Tests.ps1 (unchanged) already
covers the page's synopsis, parameters, examples, and links.

 Before 5.0.0-rc8, the cmdlet returned no access and no error when Windows refused to start the authorization manager for the computer of `-ServerName`, for example for a name of 32,718 characters or more, so that the result looked like an account without any rights. The cmdlet now writes a non-terminating `GetEffectiveAccessError` with the error that Windows reported and returns no result for the item, as it does for every other failure of the calculation. It warns that the result is based on this computer only when it calculated a result; before 5.0.0-rc8, the warning also came before an error when the computer couldn't be reached.
 
+A user who has no domain credentials, such as a local standard user, still gets the error "Access is denied" from Windows when it asks for the effective access of a user account of the domain, also for a name of this computer; the cmdlet writes it as a non-terminating `GetEffectiveAccessError` and returns no result for that item. Accounts of this computer and groups such as `Everyone` or `Domain Users` give a result.
