ocaml-migrate-parsetree.1.7.1 breaks any program using Option

[talex5]

It appears that ocaml-migrate-parsetree 1.7.1 added a new, top-level (non-wrapped) Option module. This breaks anything using the stdlib's option module. Example program:

let iter = Option.iter

and dune file:

(executable
 (name main)
 (libraries ocaml-migrate-parsetree))

This fails with:

File "main.ml", line 1, characters 8-19:
1 | let x = Option.iter
            ^^^^^^^^^^^
Error (alert deprecated): module Option
Access modules via the Migrate_parsetree toplevel module. Use Migrate_parsetree.Option instead.
File "main.ml", line 1, characters 8-19:
1 | let x = Option.iter
            ^^^^^^^^^^^
Error: Unbound value Option.iter

If the ocaml-migrate-parsetree dependency is removed, it works.
