Fix 10up-toolkit test-unit-jest command

[MyAudioDNA]

Related Issue/RFC: #480

Description of the Change

The 10up-toolkit test-unit-jest command is not working out of the box. The jest-environment-jsdom is no longer included with jest by default, which causes the jest run to fail. This includes the jest-environment-jsdom package separately to allow jest to run correctly.

Verification Process

Checked the 10up-toolkit test-unit-jest runs properly with the jest-environment-jsdom package installed separately.
