[Feature request] Provide a Compose UI element to view open source licenses

[Compose](https://developer.android.com/jetpack/compose) is the recommended UI framework for new apps. Currently the Open Source License plugin only provides an Activity, which is dependent on `Theme.AppCompat`. This means a lot of extra work is required to use this library in Compose-only apps.

It'd be great if the library could provide a `Composable`. This would make it easier to integrate with apps using Compose.
