Add Spotify data in learntidymodels

[karaesmen]

This PR adds the spotify data set and it's manual in the package.
It also removes palmerpenguins from Depends and Remotes.

Try updating from master. The PR I just merged probably solves some (hopefully all) of the issues in the tests.

The reason this is failing right now is that palmerpenguins was removed from Remotes. It is not on CRAN yet so it needs to stay in Remotes. On the other hand, embed is back on CRAN, so it can come out of Remotes.

Remotes should look like this:

Remotes:
    rstudio-education/gradethis,
    allisonhorst/palmerpenguins

Oh, unless none of tutorials are using palmerpenguins at all anymore? 🤔 In which case @karaesmen you need to remove it both from Remotes and Suggests.

Remotes is like an extra place where you say where to get a package from.

I'm going to close this very old PR 👍
