Localization is not working for REST API error responses in the Developer Portal.

[chamilaadhi]

Description

After switching to a different language, error messages still display in the original language. Error message is displayed as it is

Only the success messages are converted using i18n file. Need to handle the error responses as well.

Steps to Reproduce

1. Change the browser localization to a different language
2. Do a developer task which generates an error response (ex: create an application with name containing whitespaces)
3. Check the error pop-up message. It is displayed in english
