feat: upgrade WebdriverIO to v9, drop JWP capabilities

[web-padawan]

What I did

1. Upgraded webdriverio to v9 and changed the saucelabs launcher accordingly
2. Removed logic and docs related to JWP capabilities as these have been dropped

Note

Tested locally by running tests for @web/test-runner-webdriver package. These don't currently run in CI as they were skipped long ago, in particular due to webdriverio/selenium-standalone#788 - that issue is now fixed but unfortunately the fix landed in a version that dropped Node 18 support.

Seems fine to me. Two questions and then likely good to go.

Where does this file get this type value from? If it works, it works, but confused that there is no import. The main question is if we're doing something special somewhere else, or relying on something that I can't see, then is it visible to a more experienced WebdriverIO user in a way that would prevent their consumption of this from causing them issues?

I tried to use this but got error "Cannot use namespace 'Capabilities' as a type".

import type { Capabilities } from '@wdio/types';

The namespace is defined here, seems like it's done for supporting custom capabilities.

Does it run fine in other projects this way. I'm fine with whatever works, it was just surprising to see and would be annoying if this caused some undocumented requirements on consumers.
