Update default path and string manipulation in keystatic.config.ts

A default path for createKeyStaticConfig function is added and conditional code block entered to append '/' to the path, if it doesn't end with it. This prevents potential path issues in future codes. Also, the default value of NEXT_PUBLIC_KEYSTATIC_CONTENT_PATH is changed to an empty string from 'content'.
