What?

• Modify the ConsoleAppTesting sample project to accept a collection of URLs from the command line argument --urls.
• The project currently accepts only one URL from the command line argument --url.
• I want to be able to test multiple web addresses with the same set of test components by providing them as a comma-separated list in the --urls argument.

Acceptance Criteria

• The ConsoleAppTesting.cs project has new argument named --urls and parse it as a string array.
• The new command handler loops through the array of URLs and run the testing pipeline for each one.
