[Cleanup] Removing the un-used viewModelProviderFactoryOf from the jetcaster project.

[imjoz]

I'm not sure if clean-up PRs are accepted, as I only see templates for bug and feature requests. If this function is kept for a reason, I will close this issue.

Sample App

Jetcaster

What Happened?

Currently, the Jetcaster app uses Hilt for DI, which handles view model creation with the Hilt annotations. This makes the com.example.jetcaster.util.viewModelProviderFactoryOf() unused, as view model creation is already managed by simply using hiltViewModel().

Proposed solution

The proposal is to remove com.example.jetcaster.util.ViewModel.kt, as it is no longer needed for view model creation.
