feat: allow driversPath to be environment variable

[LukeBenting]

Purpose

Resolves #49. As documented here, Microsoft recommend that you use the Web Drivers that are preinstalled on Microsoft Hosted agents, this avoids a version mismatch between Chrome and ChromeDriver. Prior to this commit, there was no way to make use of these environment variables.

Approach

The BrowserOptions for EasyRepro allows for a driversPath variable to be provided. This commit adds logic to allow for this to be an Environment Variable. So the environment variables stated in the Microsoft Docs can be supplied. To run the ui tests for this repo locally, where the driver .exe is outputted to bin, simply create an environment variable for 'ChromeWebDriver' with a value of '.\'.

TODOs

• Automated test coverage for new code
• Documentation updated (if required)
• Build and tests successful
