feat: add organization parameter support to resetPassword API

[subhankarmaiti]

Summary

Add support for the optional organization parameter in the resetPassword API call to enable password resets within specific Auth0 organizations.

API Behavior

• When organization parameter is provided, it will be included in the request to Auth0's /dbconnections/change_password endpoint
• When organization parameter is omitted, the behavior remains unchanged (backward compatible)
• This enables password reset functionality for users within specific Auth0 organizations

Usage Example

// Reset password for a user in a specific organization
await resetPassword({
  email: 'user@example.com',
  connection: 'Username-Password-Authentication',
  organization: 'org_123'
});

// Existing usage without organization (unchanged)
await resetPassword({
  email: 'user@example.com',
  connection: 'Username-Password-Authentication'
});
