[Feature] Upgrade to Selenium 4

[tom-made]

Describe the feature

Simply, upgrading the current support for Selenium from 3 to 4.

Rationale for the feature

Noticed in the latest PR build (aab3633#annotation_7550536556)

Selenium NuGet packages are now a major version up with 4.7.0 and appears that this has been available since late 2021.

Adoption appears relatively high so we should look to upgrade and support the latest version.

Scope of the feature

• Must upgrade to support Selenium 4.x

I've investigated this a few times. Unfortunately, there isn't a stable release of Appium yet that supports Selenium 4.

@tom-made will start looking at this. Although there is no stable release yet for Appium, they have an RC which is currently on version 5.
