Description

This PR upgrades Jest to v27 and the related deps.

Jest v27 uses by default "node" environment instead of "jsdom".

Running tests in a JSDOM environment incurs a significant performance overhead. Because this was the default behavior of Jest unless otherwise configured up until now, users who are writing Node apps, for example, may not even know they are given an expensive DOM environment that they do not even need.
For this reason, we are changing the default test environment from "jsdom" to "node". If you are affected by this change because you use DOM APIs and do not have the test environment explicitly configured, you should be receiving an error when e.g. document is accessed, and you can configure "testEnvironment": "jsdom" or use per-file environment configuration to resolve this.

To handle this change, it sets testEnvironment as jsdom in jest.config.js.
