Describe the Bug

We try and follow documentation at: https://payloadcms.com/docs/beta/admin/views#document-views

livePreview The LivePreview view is used to display the Live Preview interface. It is rendered within the "Live Preview" tab. More details.

But this is not working because of missing code which should handle it. File: packages/next/src/views/Document/getViewsFromConfig.tsx - Lines 312-325

            case 'preview': {
              if (livePreviewEnabled) {
                DefaultView = {
                  Component: DefaultLivePreviewView,
                }
              }
              break
            }

            case 'versions': {
              if (!overrideDocPermissions && docPermissions?.readVersions?.permission) {
                CustomView = {
                  payloadComponent: getCustomViewByKey(views, 'versions'),
                }

The preview case is not handling the CustomView - aka:

CustomView = {
                  payloadComponent: getCustomViewByKey(views, 'livePreview'),
                }

Reproduction Steps

In payload.config.ts define next customization in one of the Collections:

components: {
      views: {
        edit: {
          default: {
            Component: '/components/views/CustomDefaultEditView',
          },
          livePreview: {
            Component: '/components/views/LivePreview/LivePreviewView'
          }
        },
      },
    }

Expected behavior is that customized live preview view will replace default live preview view , but we got the default.
