[Enhancement] - Link sample apps to tutorials

[Saif-Shines]

There are a couple of sample apps on this repository that demonstrates code used in tutorials. However, there is no way tutorials are discoverable from the sample app alone.

• [ ] Identify the common apps on the tutorials page and sample apps repository.
• [ ] The apps which seem common, add a section in the README.md file which has a link back to the tutorial.
