gulp-babel-minify on from NPM not the same as repo

**Describe the bug**

Following the installation instructions `npm i -D gulp-babel-minify` upon inspection of the module in the node_modules folder I noticed it doesn't appear to be the same as version in the repo. The version number is the same but the folder structure and the content of module appears to be different.

I noticed this due to the following bug fix:
https://github.com/babel/minify/commit/2ec8ff729eebb58a2d55d0c1b7507aaea328f80d
not being in the version on my local machine.
