Update example and demonstrate `LoopScrollMode` and `LoopActivationMode`

[wjuniorgit]

The current example in the repository is outdated and needs to be updated to showcase the usage of LoopScrollMode and LoopActivationMode in LoopPageView. This update will provide a more comprehensive understanding of the library's capabilities and options.

Additionally, it would be beneficial to include examples that demonstrate both horizontal and vertical scrolling.

This issue is tagged as a 'good first issue' to encourage new contributors to get involved in the project. It provides an opportunity to make a meaningful contribution by updating the example code and ensuring it reflects the latest features and best practices of LoopPageView.
