fix(lint): Remove extra space (#6517)

## Problem
A line in
[packages/core/package.nls.json](https://github.com/aws/aws-toolkit-vscode/compare/master...witness-me:fix-lint?expand=1#diff-4d90099a916e267c6fa8cfeeec9c569c4889dc50cb53178e1c748d0d37ff501e)
contains extra space, which is inconsistent with current code style

## Solution
Remove extra space

- License: I confirm that my contribution is made under the terms of the
Apache 2.0 license.
