Typo in image label in tutorials

[dap6000]

See this image -> https://docs.nativescript.org/assets/images/tutorial/tutorial-example-app-details-breakdown.png

Has a label that says "Here Image" while the tutorial text refers to it as the "Hero Image". The assets/images/tutorial/ directory doesn't seem to exist here in the repo. I'm not sure what it would take to replace the image in production.

@williamjuan027 you might have the source file to fix it? Here Image -> Hero Image
