feat: webauthn (#583)

### Adds Webauthn (Passkeys) support
- Adds Webauthn recipe with support for:
  - Registration, sign-in, and credential verification flows
  - Account recovery
- Adds new API endpoints for WebAuthn operations:
  - GET `/api/webauthn/email/exists` - Check if email exists in system
  - POST `/api/webauthn/options/register` - Handle registration options
  - POST `/api/webauthn/options/signin` - Handle sign-in options
  - POST `/api/webauthn/signin` - Handle WebAuthn sign-in
  - POST `/api/webauthn/signup` - Handle WebAuthn sign-up
  - POST `/api/user/webauthn/reset` - Handle account recovery
  - POST `/api/user/webauthn/reset/token` - Generate recovery tokens
- Adds WebAuthn support to account linking functionality:
  - Support for linking users based on WebAuthn `credential_id`
  - Updates `AccountInfo` type to `AccountInfoInput` with WebAuthn fields
  - Adds `has_same_webauthn_info_as` method for credential comparison
- Adds FDI support for version `4.1`
- Recipe functions are directly importable from the Webauthn recipe module
  - ```python
    from supertokens_python.recipe.webauthn import sign_in

    await sign_in(...) # Async
    sign_in.sync(...) # Sync
    ```

### Breaking Changes
- Updates supported CDI version from `5.2` to `5.3`
- Changes `AccountInfo` to `AccountInfoInput` in various methods
  - This is required to allow querying by a single Webauthn `credential_id`, while the Webauthn login method contains an array of `credential_ids`
  - Affected functions:
    - `supertokens_python.asyncio.list_users_by_account_info`
    - `supertokens_python.syncio.list_users_by_account_info`
    - `supertokens_python.recipe.accountlinking.interface.RecipeInterface.list_users_by_account_info`
    - `supertokens_python.recipe.accountlinking.recipe_implementation.RecipeImplementation.list_users_by_account_info`
