Need to update regex for {{copy}} Multiline Clipboard Copy on patternfly QuickStarts

Issue

Multiline clipboard {{copy}} fails to render correctly in case of indentation

Fix

The regex for {{execute}} command has been updated in Openshift Console

From regex: /```[\n]((.*?\n)+)```{{execute}}/g,
to regex: /```[\n]\s*((((?!```).)*?\n)+)\s*```{{execute}}/g,

Reference

Refer https://github.com/openshift/console/pull/11572 for fixing
