Document connection-based sign-up in self-registration flow

[DilshanSenarath]

Purpose

Document how to add a connection-based (social/enterprise) sign-up option to the self-registration flow, and update the flows overview to reflect that self-registration supports external connections.

Changes

• en/includes/guides/flows/index.md: Note that self-registration supports signing up through supported connections (Google, Apple, Facebook, Microsoft, GitHub).
• en/includes/guides/flows/self-registration.md: Replace the standalone redirect-URL note with a new Add a connection-based sign-up option section that lists the supported connections, links to their setup guides, and walks through registering the connection, configuring the authorized redirect URL, and wiring up the Continue with {Provider} widget in the Flow Builder.
