Cli: [BUG] npm publish tarball에 `ENOTDIR: 디렉토리가 아님` 오류가 발생했습니다.

현재 행동:

npm publish /path/to/tarball/from/npm-pack.tgz 와 같은 명령을 사용하면 npm에서 다음과 같은 오류가 발생합니다.

$ npm publish ./dr-js-core-0.4.0-dev.8.tgz
npm ERR! code ENOTDIR
npm ERR! syscall open
npm ERR! path ./dr-js-core-0.4.0-dev.8.tgz/package.json
npm ERR! errno -20
npm ERR! ENOTDIR: not a directory, open './dr-js-core-0.4.0-dev.8.tgz/package.json'

예상되는 동작:

tarball을 게시해야 하는 경우 현재 npm은 이것이 npm pack 를 실행할 폴더라고 생각하는 것 같습니다.

재현 단계:

다음으로 테스트할 수 있어야 합니다.
```쉘 스크립트
mkdir -p ./test-npm-게시
cd ./test-npm-게시
npm 초기화 --예
npm 팩
npm 게시 테스트-npm-publish-1.0.0.tgz

### Environment:
<!--
ex.
- OS: Ubuntu 20.04
- Node: 13.14.0
- npm: 6.4.12

27 상세 노드 v15.0.1
