Published package is too large

🐞 Describe the Bug

While working on the Prettier plugin for hbs tags, I noticed that prettier-plugin-ember-template-tag stands at 3.73 MB, cause it publishes all files from the repo. There is an .npmignore file, so the publish step doesn't seem to be working as intended. The 2nd link shows all that's needed for a Prettier plugin.

• https://www.npmjs.com/package/prettier-plugin-ember-template-tag?activeTab=code
• https://www.npmjs.com/package/prettier-plugin-ember-hbs-tag?activeTab=code

It looks like #345 had been merged, but not released.
