-   [ ] Refactor
-   [ ] Documentation
-   [x] Other (describe) 

## 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
