embark-api: Upgrading Helmet to the next major version

[EvanHahn]

I'm the maintainer of Helmet. I plan to release the next major version this Sunday, 2020-08-22.

Is there anything I can do to help get this project upgraded to helmet@4?

If you'd like to try out the release candidate now, you can install it with npm install helmet@next. If you'd rather discuss things outside of this issue, feel free to reach out to me another way.

Hope I can be helpful!
