Upgrade jest and all related dependencies to latest 29.x

[cee-chen]

We're streets behind and should probably grab the latest Jest version(s). List of dependencies that will need upgrading:

• jest
• jest-cli
• @types/jest
• babel-jest
• eslint-plugin-jest

This PR was not grabbed as part of #6652 as I believe @tkajtoch has some in-progress Jest upgrade work as part of the React 18 upgrade (#6182).
