Fixes Typings and Upgrades Packages (#14)

* Fixes is Typings

The `getType` output type was set to boolean, when it should have been
string, and `getType` was defined on `not` in the Type file, but it
isn't defined there in JS.

* Upgrades Packages

Upgrades all packages, but more specifically, gets the latest
eslint-utils to address [GHSA-3gx7-xhv7-5mx3](GHSA-3gx7-xhv7-5mx3)
