test(browser): Port unhandledrejection tests to playwright (#11758)

ref #11084

This test ports
`packages/browser/test/integration/suites/onunhandledrejection.js`
playwright. Because of the same limitations as outlined with the on
error tests #11666, I
had to use calls to `window.onunhandledrejection` to simulate these
tests instead of just using `Promise.reject` to test the handler.

#11678 tracks being
able to fix this so we can avoid directly calling
`window.onunhandledrejection` to test.

As `onunhandledrejection.js` was the last suite to use the old
integration tests, I fully removed that code and the corresponding GH
action workflow. I also removed the monorepo deps on `karma`, `chai` and
`sinon`. Extremely satisfying.
