feat: add ory provider

[Jorgagu]

This pull request introduces support for Ory OAuth integration in the project. The changes include updates to configuration files, new functionality for handling Ory OAuth flows, and adjustments to existing code to accommodate the new provider.

Ory OAuth Integration:

• New Ory OAuth handler: Added ory.ts in src/runtime/server/lib/oauth/ to implement the Ory OAuth2 authorization code flow, including configuration options, token handling, and user information retrieval.
• Updated runtime configuration: Modified src/module.ts to include Ory-specific OAuth settings such as clientId, clientSecret, sdkURL, and URLs for authorization, token, and userinfo endpoints.

Configuration Updates:

• Environment variables for Ory: Added Ory-specific environment variables (NUXT_OAUTH_ORY_CLIENT_ID, NUXT_OAUTH_ORY_CLIENT_SECRET, NUXT_OAUTH_ORY_SDK_URL) to playground/.env.example.

UI Enhancements:

• Ory provider in UI: Updated playground/app.vue to include Ory as an available OAuth provider, with its label, route, and icon.

Documentation and Types:

• Added Ory to supported providers: Updated README.md and src/runtime/types/oauth-config.ts to include Ory in the list of supported OAuth providers. [1] [2]
