raylib screenshots: setup, reset, updater

[TheSecurityDev]

Adds screenshots for most states of the setup, reset, and updater screens. Most of the code is in the system for running these new types of tests (separate UI script), so once you have it, adding the tests for all 3 scripts doesn't add much complexity.
