Describe the problem
I was trying to access a link in the @patternfly/patternfly-react README but encountered a few "Not found" errors on clicking

How do you reproduce the problem?

1. Go to this repository's homepage on GitHub and scroll down to the README
2. Click any of the affected links (@patternfly/react-log-viewer, @patternfly/react-catalog-view-extension, @patternfly/react-topology, @patternfly/react-virtualized-extension)
3. Observe the links are broken

Expected behavior
They do not break

Is this issue blocking you?
No
