What happened?

When creating a project from scratch in an existing project that uses Yarn workspaces the wdio config command fails installing the dependencies because of a missing -W, e.g.:

Installing wdio packages:
- @wdio/local-runner
- @wdio/mocha-framework
- @wdio/spec-reporter
- wdio-vscode-service
yarn add v1.22.17
error Running this command will add the dependency to the workspace root rather than the workspace itself, which might not be what you want - if you really meant it, make it explicit by running this command again with the -W flag (or --ignore-workspace-root-check).
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.
An unknown error happened! Please retry installing dependencies via "yarn add --dev @wdio/local-runner @wdio/mocha-framework @wdio/spec-reporter wdio-vscode-service"

What is your expected behavior?

We should check within the package.json if workspaces are being used and either add a -W to the install statement or ask the user whether to add it to one of the sub-packages.

How to reproduce the bug.

Create a project that uses Yarn workspaces and try to run the WDIO wizard on it.

I got a similar error right now:

command run npx wdio . --yes

Documentation: https://webdriver.io
@wdio/cli (v7.19.2)

I believe the plugins property in our questionnaire object needs a default value as empty array.

@cschar wanna help us take a stab at this?

@Angela0508 hey 👋 it seems you are trying to install an old WebdriverIO version that comes with fibers which we don't support anymore. I recommend updating you WebdriverIO version to latest.
