The Angular Compiler requires TypeScript >=4.4.2 and <4.7.0 but 4.7.4 was found instead.

When checking out the repo and running 
```yarn install``` followed by
```yarn run test```

example-browser-angular crashes with the error: 
``` 
throw new Error(`The Angular Compiler requires TypeScript >=${minVersion} and <${maxVersion} but ${version} was found instead.`);
          ^

Error: The Angular Compiler requires TypeScript >=4.4.2 and <4.7.0 but 4.7.4 was found instead.
