Improvement: Make audio description selectable on the details screen

🎩 What is the problem?

Currently, the content/description displayed in the details screen is not selectable, therefore the user can't copy relevant information like links.

:tophat: How was this resolved?

Implementing SelectionContainer and wrapping it by creating a new composable: SelectableEmphasisText

Thanks, @soyjimmysaenz!! It works like a charm!
