Add new examples that make use of https://seleniumbase.io/simple/login

There's a new website just for testing basic login and showing off SeleniumBase methods and features.

We still have the existing MFA (Multi-factor auth / 2FA) site here: https://seleniumbase.io/realworld/login.

(The sites are nearly identical, but the new one removed the MFA part to make some examples simpler.)

This was resolved in 4.18.9 - https://github.com/seleniumbase/SeleniumBase/releases/tag/v4.18.9
