dictionary-en-us is deprecated

[german1608]

In the official package page of dictionary-en-us it says that https://www.npmjs.com/package/dictionary-en-us the package was deprecated. Although it says that the deprecated version is 3.0.0 and our version is 2.1.1 since our package.json it will be a good idea to do the migration to dictionary-en.

Also, we might need to update other dictionaries to their latest versions:
