Add Embedded Wallet Generation During User Sign-Up with Supabase Auth

[tcxcx]

I would like to propose adding support for embedded wallet generation during the user sign-up process using Supabase Auth with compatibility with Social providers including Google and Github. Currently, the documentation and examples primarily reference Firebase for this functionality.

Proposed Solution

• Implement a built-in method or provide comprehensive documentation on how to integrate embedded wallet generation with Supabase Auth.
• Provide example repositories or code snippets that demonstrate this integration.
• Extend support to Circle, if applicable, to offer more flexibility for developers using different platforms.

Benefits

• Enhances the user onboarding experience by seamlessly generating wallets during registration.
• Broadens the functionality and appeal of Supabase Auth to developers who prefer or are already using Supabase over Firebase.
• Addresses a common need within the community, potentially increasing adoption and satisfaction.
