bugfix: schema updation issue

in standalone mode, the `.schema` file from staging wasn't getting pushed to storage due to the improper usage of `path().extension()` function.
It was always returning `None`. Instead of checking whether the extension is `schema`, check if the file path ends with `.schema`
