What is the purpose of this PR?

This PR prepares the Yeoman widget generator for replacing the Enzyme for testing in favor of RTL, the React Testing Library.

Relevant changes

• The generator for web package.json is adjusted to remove enzyme as a dependency
• The react-dom dependency is added to resolutions and overrides as RTL required it
• The scaffolded unit tests when the user chooses the unit test option are adjusted for RTL
• Generator tests are adjusted
• A bonus fix for updating the copyright year is included.

What should be covered while testing?

• Both the options with unit test and e2e should be tested
• The generator tests must be green
• The default tests that arrive with a scaffolded widget should be green

REMAINING:

• Check native
• Check e2e tests
• PWT Workflow Actions seems to be failing for the PR
• One issue is that, the scaffolded widget is not able to run the unit tests before npm install is run
• Check if we can get rid of the non-enzyme config in PWT
• Add a check in PWT to detect and warn on enzyme tests (grepping on enzyme imports will do probably)
• Mention as breaking change in release notes
• Check docs
