Fix deprecated function getCurrentUserId replaced by getDefaultEntityOwner in core.base_field_override.node.varbase_heroslider_media.uid config for Drupal 9 compatibility

Problem/Motivation

The default config file core.base_field_override.node.varbase_heroslider_media.uid.yml
has default_value_callback: 'Drupal\node\Entity\Node::getCurrentUserId'
But getCurrentUserId is deprecated in Drupal 9

Deprecated
The ::getCurrentUserId method is deprecated in 8.6.x and will be removed before 9.0.0.

Proposed resolution

From

default_value_callback: 'Drupal\node\Entity\Node::getCurrentUserId'

To

default_value_callback: 'Drupal\node\Entity\Node::getDefaultEntityOwner'
and have a hook update function

• Update for core.base_field_override.node.varbase_heroslider_media.uid
• And all content types in the active config.
