Undefined array key "#view_mode"

Problem/Motivation

Using the SDC Display module to render a paragraph causes the following warning:

Warning: Undefined array key "#view_mode" in Drupal\paragraphs\ParagraphViewBuilder->buildMultiple()
(Line 23 in .../web/modules/contrib/paragraphs/src/ParagraphViewBuilder.php)

Except of the warning everything works fine as expected. (Thank you for this great module :) )

Steps to reproduce

Configure a paragraph type with just the default display mode and assign its fields to a sdc component. Using the paragraph type on any node type leads to the warning.

Proposed resolution

It seems to be caused by paragraphs function that expected the "#view_mode" key in the build array. Adding the key in sdc_display_entity_view_alter solves the issue for me.

Is this the right way of fixing this? Or should paragraphs test for the key?
