[eslint config] [base] [deps] Switch to confusing-browser-globals

The `eslint-restricted-globals` package author created an equivalent
package `confusing-browser-globals` that now resides within the
create-react-app monorepo. In sidoshi/eslint-restricted-globals#2
@sidoshi suggested that we change eslint-config-airbnb-base to depend
on the CRA package instead, in an effort to consolidate the two.

Currently the two global lists are identical, so this does not change
the generated eslint config:
