docs: Reports the last element of a given node if it does not have a trailing
  comma.
  
  If a given node is `ArrayPattern` which has `RestElement`, the trailing
  comma is disallowed, so report if it exists.
  
  @param {ASTNode} node - A node to check. Its type is one of
  ObjectExpression, ObjectPattern, ArrayExpression, ArrayPattern,
  ImportDeclaration, and ExportNamedDeclaration.
