Could we just have the whole page loading using a skeleton loader?

Except for the ratings, there is nothing that needs loading on the package page.
If the styling of the shimmer effect is a no-go, I can update it.

@BLKKKBVSIK, I think it looks odd using the skeleton (shimmer) just on the ratings, as it's only loading a tiny fraction of the screen.
I think we should force the whole section to be skeleton until everything in there is ready to be loaded (in this case, ratings).
It's more perceptive that it's loading information, and the order we want users to read the content is kept (ratings first)

However, all the other information is available immediately and doesn't need any loading indicator. It'd be a shame if we had to add a skeleton loader just because of the ratings 😢

Let's merge this as discussed :D
