[py] add links to documentation for errors

[titusfortner]

Description

• Have exceptions link to documentation
• Create custom Error for Driver Location that links to docs
• Driver Finder gives different error message if Selenium Manager code errors
• SeleniumManager throws WebDriverExceptions, which are caught by DriverFinder & raised as NoSuchDriver exceptions
• Catches additional potential exceptions in Selenium Manager

Motivation and Context

• We want to give the user the most accurate info in their error messages when there is a problem and link to more info if necessary
• This brings the logic in line with Java & Ruby
