React Code Editor - Replace `react-monaco-editor` with `@monaco-editor/react`

[jonkoops]

The react-monaco-editor package should be replaced with @monaco-editor/react. The latter is much more mature and receives more frequent updates, specifically:

• It has much better documentation
• Doesn't need a WebPack plugin
• Has a stable version

I think this would be a good candidate for the next major version of PatternFly React.

[jonkoops]

Alternatively a new package could be created and published under a new major of @patternfly/react-code-editor. The 'legacy' version could then be published under a new @patternfly/react-code-editor-legacy package to provide a migration path.

Consider for post v5 as an Editor-Next component.
