adding test-specific tsconfig files in appropriate dirs

[ATorrise]

What It Does
Configures typescript test files to include jest type information, reducing the amount of distracting, not-real-yet-still-highlighted-as-such errors when working in test files

How to Test
Pull branch and start opening up some test files, making sure there are no errors like:

Cannot find name 'describe'. Do you need to install type definitions for a test runner? Try `npm i --save-dev @types/jest` or `npm i --save-dev @types/mocha`.ts(2582)

TL;DR: LGTM! 😋

---

I like this solution a lot.
It resolved the problem of having to import @types/jest in a random file for those Jest functions (describe, afterAll, ...) to be recognized as actual functions.

I'm curious if we could do some technique to reduce duplication. Something like...

"extends": "../../tsconfig.json",

One thing to keep in mind that this only fixes tests that are under the packages/PKG/__tests__/ directory. For example, this won't help with
packages/imperative/src/utilities/__tests__/CliUtils.unit.test.ts since the tsconfig.json is under packages/imperative/__tests__/ 😋

I take that back.
Even files from within the imperative/src/utilities/__tests__/ work now 😋
