docs: clarify custom roles require Enterprise plan

[devin-ai-integration]

Context

The RBAC docs page describes custom roles without mentioning they require an Enterprise license. This causes confusion for free self-hosted users who see RBAC marked with a red X in Usage & Billing but read the docs as if custom roles are available to everyone.

Adds an <Info> callout to the "Creating custom roles" section clarifying that custom roles require the Enterprise plan, while built-in roles (Admin, Member, Viewer, No Access) are available on all plans including free self-hosted.

Steps to verify the change

1. Visit https://infisical.com/docs/documentation/platform/access-controls/role-based-access-controls
2. Confirm the Info callout appears above the "Creating custom roles" content

Greptile Summary

This PR adds a single <Info> callout to the RBAC documentation page to clarify that custom roles are an Enterprise-only feature, addressing confusion for free self-hosted users.

• Inserts an <Info> block directly above the "Creating custom roles" section content, clearly stating that built-in roles (Admin, Member, Viewer, No Access) remain available on all plans including free self-hosted.

Confidence Score: 5/5

This is a docs-only change with no code impact; it is safe to merge.

The change is a single four-line addition to an MDX documentation file. The callout is placed accurately, the text is factually consistent with the rest of the RBAC docs, and no code paths are affected.

No files require special attention.
