#53102: Incorrect documentation for delete_{$meta_type}_meta and
deleted_{$meta_type}_meta filter hooks

--------------------------+-----------------------------
 The inline documentation for `delete_{$meta_type}_meta` and
 `deleted_{$meta_type}_meta` incorrectly states that the `$_meta_value`
 parameter is `Serialized if non-scalar` (from [47390]). While
 `$meta_value` is run through `maybe_serialize`, `$_meta_value` is not.

 Also, I think the hook documentation should make it clear that the meta
 value is only passed from the optional function argument, so it might not
 contain anything meaningful.
