Example command in README doesn't run all `.js` files

[drewdaemon]

I have verified that

npx github:ember-codemods/es5-getter-ember-codemod es5-getter-ember-codemod app/**/.js

does not pick up .js files at all levels of the file tree. It seems to act like app/*/*.js instead.

npx github:ember-codemods/es5-getter-ember-codemod es5-getter-ember-codemod app/**/**/.js

Picks up a different set of files.

However

npx github:ember-codemods/es5-getter-ember-codemod es5-getter-ember-codemod app/

does pick everything up.
