As a user, I want Xray REST API status code is showing 403 instead of 400 when user do not have permissions to create issues

Currently, Xray REST APIs are showing correct error text, however, some response Status needs to be changed.

Steps to reproduce:

• Take an Xray project in which the user does not have permissions to create issues
• Import Cucumber feature files into the project using REST API.

• curl -H "Content-Type: multipart/form-data" -X POST -H "Authorization: Bearer $token" -F "file=@1.feature" https://xray.cloud.getxray.app/api/v1/import/feature?projectKey=DEMO 

• Check for the Status response of the REST API

It is expected that the status code should be 403(forbidden error) due to insufficient permissions, however, we get 400 error code.
