Document voice muting based on player blocks guide (#8319)

Adds a new how-to guide covering bi-directional voice muting in lobby voice
calls based on block relationships. Covers two approaches for populating
per-member mute lists — client-side using any client-accessible block signal
(Discord relationships, in-game block lists, etc.) and server-side via lobby
member metadata set at lobby creation — with a shared C++ implementation that
applies mutes in both directions using lobby member metadata.

Also documents the POST /lobbies/{lobby.id}/members/bulk endpoint for adding,
updating, or removing up to 25 lobby members in a single request.

+  ## Voice Muting Based on Player Blocks
+
+  We've published a new how-to guide covering how to implement bi-directional voice muting in lobby voice calls based on block relationships. The guide covers two approaches for populating per-member mute lists — client-side using any client-accessible block signal (Discord relationships, in-game block lists, etc.) and server-side via lobby member metadata set at lobby creation — and a shared client-side implementation that applies mutes in both directions.
+
+  As part of this work, we've also documented the [`POST /lobbies/{lobby.id}/members/bulk`](/developers/resources/lobby#bulk-update-lobby-members) endpoint, which allows adding, updating, or removing up to 25 lobby members in a single request.
