Remove Group Policy Assignment (GPA) content from Grant-CsDialoutPolicy

[d-chetan]

Summary

Grant-CsDialoutPolicy currently documents a Group Policy Assignment (GPA) path — the GrantToGroup parameter set with -Group and -Rank. Group Policy Assignment does not support the outbound calling restriction policy (OnlineDialOutPolicy), so this content is inaccurate and can mislead admins into attempting group-based assignment that isn't supported.

Evidence (public documentation)

The authoritative list of GPA-supported policy types is the -PolicyType parameter of Get-CsGroupPolicyAssignment. That enumeration includes the sibling voice policies — OnlineVoiceRoutingPolicy, OnlineVoicemailPolicy, OnlineAudioConferencingRoutingPolicy, TeamsSharedCallingRoutingPolicy, CallingLineIdentity, and TenantDialPlan — but does not include OnlineDialOutPolicy. Because Dialout is absent while its sibling voice policies are present, GPA is not supported for this policy type.

Changes

Removed all GPA references from Grant-CsDialoutPolicy.md and added an explicit callout that GPA is unsupported:

• SYNOPSIS — removed "a group of users,"
• SYNTAX — removed the GrantToGroup parameter set
• EXAMPLES — removed Example 5 (-Group / -Rank)
• PARAMETERS — removed -Group and -Rank
• NOTES — removed the GrantToGroup version note and added a callout stating that group policy assignment is not supported for the Dialout policy

Admins should continue to use per-user (-Identity) or tenant global (-Global) assignment for outbound calling restriction policies.
