Composer files seem to be out of date

[kiwiFella]

Instructions on this page Lesson Content say to run "composer install" in each "lesson-begin" directory.

However running composer install (or composer update) fails to load dependencies & install completely and creates errors when running in browser... it appears that the composer file settings are significantly out of date - Running "composer install" says it's out of date... then running "composer update" writes to the composer.json file to include the old "mysite" + "mysite/code" directories under "extra -> project-files-installed" ... even thou the silverstripe/lessons git repo's folder structure has already been changed from mysite to app (the composer file appears to create a mysite directory and write to the composer.json file)

This creates an error when trying to run silverstripe-lessons in the browser...

Fatal error: Uncaught Exception: There are two files containing the "Page" class: "C:\www\silverstripe-lessons-v4\Lesson-04-begin/app/src/Page.php" and "C:\www\silverstripe-lessons-v4\Lesson-04-begin/mysite/code/Page.php"

These lessons are an amazing learning resource - please update them so we can continue to enjoy learning SS.
