### Why?
I really dislike the way `.chain` works right now, it shouldn't mutate
the `BrowserInterface`, this PR changes it so it's just a pure chain
without weird side effects.
One example with the current version (before this PR):
```
const el = browser.elementByCss('#version-2')
await el.text()
// throws
await el.text()
```
### Additional Changes
- removes selenium (which is completely unused)
- updates playwright
- makes the playwright tracing not error all the time
