[BottomSheet] sample can't be built, docs and sample don't match, and missing information of edge-to-edge

[AndroidDeveloperLB]

Description: Full description of issue here
Right now, if you check the sample "catalog" and reach the bottom sheet code, you will see it's quite old, not matching the docs, and even reaches protected API of the library:

material-components-android/catalog/java/io/material/catalog/bottomsheet/BottomSheetScrollableContentDemoFragment.java

Line 57 in 629e24f

@SuppressWarnings("RestrictTo")

The docs say to use "enableEdgeToEdge " and setting "navigationBarColor" to be transparent, but the sample doesn't have any of these:

https://github.com/material-components/material-components-android/blob/master/docs/components/BottomSheet.md#setting-behavior:~:text=On%20API%2021%20and%20above%20the%20modal%20bottom%20sheet%20will%20be%20rendered%20fullscreen%20(edge%20to%20edge)%20if%20the%20navigation%20bar%20is%20transparent%20and%20app%3AenableEdgeToEdge%20is%20true.%20To%20enable%20edge%2Dto%2Dedge%20by%20default%20for%20modal%20bottom%20sheets%2C%20you%20can%20override%20%3Fattr/bottomSheetDialogTheme%20like%20the%20below%20example%3A

Not to mention the sample doesn't even build fine, so I can't run it to see how well it works other than using the release-apk of the repository.

Expected behavior: Screenshots and/or description of expected behavior

1. The sample should match the latest APIs that are documented and recommended.
2. The sample should be built fine using latest Android Studio version.
3. The docs should mention what it means app:enableEdgeToEdge is true, because it doesn't show it in the snippets and doesn't mention it anywhere there, of where to put it.
