webdriverio peer dep needs to be updated to include v9

[smackfu]

Product

webdriverio

Product Version

4.10.0

Latest Version

• I have tested the issue with the latest version of the product

Issue Description

Expectation

If I have the latest version of webdriverio installed, I would expect @axe-core/webdriverio to use it and not get a peer dep error.

Actual

Peer dep list only include v8 so there is a peer dep error.

$ npm install --save-dev @axe-core/webdriverio@latest
npm error code ERESOLVE
npm error ERESOLVE unable to resolve dependency tree
npm error
npm error While resolving: example@1.0.0
npm error Found: webdriverio@9.2.1
npm error node_modules/webdriverio
npm error   dev webdriverio@"^9.2.1" from the root project
npm error
npm error Could not resolve dependency:
npm error peer webdriverio@"^5 || ^6 || ^7 || ^8" from @axe-core/webdriverio@4.10.0
npm error node_modules/@axe-core/webdriverio
npm error   dev @axe-core/webdriverio@"4.10.0" from the root project
npm error
npm error Fix the upstream dependency conflict, or retry
npm error this command with --force or --legacy-peer-deps
npm error to accept an incorrect (and potentially broken) dependency resolution.

How to Reproduce

1. npm init
2. npm install --save-dev webdriverio@latest
3. npm install --save-dev @axe-core/webdriverio@latest

Additional context

webdriverio was bumped to v9 on Aug 15, and has had several releases so should be stable by now:
