[dependabot]

Bumps approvals from 6.2.1 to 7.1.0.

Release notes

Sourced from approvals's releases.

Support for VS Codium

Added a reporter for vs codium

Thanks to @​stevendkwtz

Typescript

There should be no visible changes from this release ¯_(ツ)_/¯ But all of the source files have been upgraded to typescript.

Normally I would set this as a patch release, but I making it a major version as I am concerned about changes to have javascript and typescript handle exports.

I have had to use the following a bit

Imports

var a = require("a")
⇓
import {a} from "a"
or 
import * as a from "a"
Fix JestReporter importing full class instead of type
For the future, we have set "importsNotUsedAsValues" to "error" to prevent future recurrences.
This helps other packages that have this value set not error-out because they are using Approvals.
fix version number in npm package
Fixes #150
the 'v' in v6.2.3 caused trouble with npm
Minor bug with Angular + Jest
Added check when running JestApprovals in angular

Looks like approvals is up-to-date now, so this is no longer needed.
