class OptionalContextCondition in Drupal 9

Provides a condition with an optional node context.

The context type entity:node is used since that would allow to also use this for web tests with the node route context.

Plugin annotation

@Condition(
  id = "condition_test_optional_context",
  label = @Translation("Optional context"),
  context_definitions = {
    "node" = @ContextDefinition("entity:node", label = @Translation("Node"), required = FALSE),
  }
)
