Implement update my profile endpoint

Description: This issue involves implementing an API to update the profile details. The endpoint should allow clients to make a PUT request to {{baseUrl}}/api/me.

sample response body:

{
    "created_at": "2023-06-29T09:15:00Z",
    "updated_at": "2023-06-30T16:45:00Z",
    "primary_email": "mentor@example.com",
    "contact_email": "mentor_contact@example.com",
    "first_name": "John",
    "last_name": "Doe",
    "image_url": "https://example.com/mentor_profile_image.jpg",
    "linkedin_url": "https://www.linkedin.com/in/johndoe",
    "type": "DEFAULT",
    "uuid": "12345678-1234-5678-1234-567812345678"
}

Tasks:

Create a controller for the /controllers/profile endpoint in the backend (create the route profile if not created).
Parse and validate the request body to ensure it matches the expected format.
Implement appropriate error handling and response status codes for different scenarios (e.g., validation errors, database errors).
Write unit tests to validate the functionality and correctness of the endpoint.
