Fix Go lang spec: correct stale node types, add func_literal

- func_types: add func_literal (anonymous functions/closures)
- branch_types: fix 3 stale names:
  switch_expression → expression_switch_statement
  case_clause → expression_case
  default_clause → default_case
- branch_types: add type_switch_statement, type_case,
  communication_case, defer_statement, go_statement
