Bug - [Alert] - Spacing on Alert examples page is not right

[mcarrano]

Describe the problem
Somehow the spacing within examples on the Alert component page has changed. See this screenshot.

Note that there are two problems here.

1. There should be space between the alert variants.
2. The formatting of the table under Alert variants is lost.

Compare with https://www.patternfly.org/v4/components/alert

FWIW, the table spacing is not specific to Alert, and is an issue across the board in the documentation. Another example of the table format being less than ideal can be seen here: http://patternfly-react-v5.surge.sh/components/button
