User Resource improvement on bad request

[bryanboza]

Problem Statement

When sending a bad request to the user resource in dotCMS, the API is returning the same error message twice in the response, leading to redundant error handling and potential confusion for users.

API :http://localhost:8080/api/v1/users

Body:

{
    "active":true,
    "firstName" : "lala",
    "middleName":"MaxtLengtOnName-aBC1dEF2gHI3jKL4mNO5pQR6sTU7vWX8yZA9bCD0eFGhIJkLMnOPqRsTtUVwXYzABCDEFGHIJKLMNOQRSTUVWXYZ123",
    "lastName":"Spanish",
    
    "password":["1","2","3","4","5","6","7","8"]
}

Steps to Reproduce

• Send a bad request to the user resource endpoint in dotCMS. (exclude a required parameter)
• Observe the response for duplicate error messages.

Acceptance Criteria

• Single Error Response: Ensure that the API returns a single error message in the response for a bad request to the user resource.
• Clear Error Message: The error message should clearly indicate the nature of the error and provide guidance on how to resolve it.
• Consistent Error Handling: The API should handle bad requests consistently across all user resource endpoints.
