[Sample] Request: update sample to better demonstrate website material design samples

Nobody has claimed this yet.

**Is your feature request related to a problem? Please describe.**
Yes, there is a huge gap between what's shown on the material design guidelines of what's possible and beautiful examples, vs what's shown here (which can be complicated yet still not the same):
https://m2.material.io/components?platform=android
https://github.com/material-components/material-components-android/tree/master/catalog

**Describe the solution you'd like**
For each screenshot and animation on the website, actually show how you did it, meaning have a link on the official website to the sample/file to reach, so that each time we see something nice, we could reach it and learn from it, how it's recommended to use it.
What's the point in demonstrating things of a library, yet not showing the source of how you did it...
I'm sure the same thing is true for the other platforms and frameworks too.

**Describe alternatives you've considered**
Some things can be done easily, and I personally prefer minimal examples first, but here we didn't get minimal ones AND what's shown on the official website.

**Additional context**
Example is of Bottom sheet:
https://m2.material.io/components/sheets-bottom#behavior

Compare this bottom sheet which has a FAB at the top, and gets disappeared when expanding, taking full screen:
[Bottom sheets full screen.zip](https://github.com/user-attachments/files/16478753/Bottom.sheets.full.screen.zip)

With this sample we have:
[scrcpy_2024-08-03_12-37-39.zip](https://github.com/user-attachments/files/16478958/scrcpy_2024-08-03_12-37-39.zip)

Start by comparing the linked Material Design bottom-sheet example, the existing sample referenced in the issue, and the Material Components catalog. No repository file or test is named, so the implementation entry point must first be identified. Done would require an agreed scope and links from the website to source samples for the showcased screenshots and animations.
