Bug: Audit and update bulk selector behavior across React demos.

[edonehoo]

Creating a follow-up for patternfly/patternfly-org#4620

Original description:

A number of react demos on our site [filter pattern examples, card view demo, primary/detail card view demo, and table with bulk select demo] do not match the behavior noted in our design guidelines & are inconsistent. Addt'l react follow up issue needed.

These demos may just need an audit in general, but Lucia may have more context on specific discrepancies.
