message: maintenance4: Fix documented output parameter now named `out`
  This naming was changed at the last resort across the other `_len()`
  variant calls to be consistent, but the maintenance4 PR didn't have its
  documentation updated (probably some rust-analyzer "rename symbol"
  action).
  Fixes: ("extensions: Add VK_KHR_maintenance4")
