Adminlte: Card- * styles do not work

[calvarezm70]

It seems that the card-primary card-success card-warning card-danger styles were removed.

[calvarezm70]

Reviewing I found that there are other bg- * classes that help change colors.

For example.
<div class = "card-header bg-primary"> Header </div>

What should be corrected then are the examples that appear on the Widgets page.

I guess the card-outline no longer works.

I've fixed the bug in the master repo, I'll release v3.0.1 soon with this fix.
