docs: remove the Early Access callout from group-based tool access (PLT-3234) (#1208)

group_access now ships generally available (ArcadeAI/monorepo#4576), so it is
no longer turned on per organization.

 # Group-Based Tool Access

-  **Early Access.** Group-based tool access is off by default and turned on per
-  organization. Contact Arcade support to have it enabled for yours. While it is
-  off, the group access extension type is not offered in the Dashboard and the
-  API refuses to create one.

 As a platform operator, you can vary which tools a caller sees based on their identity provider groups. Group-based access is built into the Arcade Engine: you define rules that require membership in a group, and the Engine checks membership and filters the tool list before the caller sees it. Like [rate limits](/operate/governance/contextual-access/rate-limiting), it runs natively inside Arcade, so there is no server to build or host.
 
 Use it when one MCP gateway serves more than one team or customer and they should not all see the same tools, instead of running a separate gateway for each.
