Resolve issues with remote Edge personalities; fix 'runGrid' task

In this release, I resolved issues with the personality declaration for the Microsoft Edge browser. The ms:edgeChromium capability is version-specific to Selenium 3 and specifying this capability in a "new session" request to a Selenium 4 grid results in slot matching failure. In the process of diagnosing this issue, I discovered that the runGrid task of the project build script didn't actually work. This issue has also been resolved.
