MDX does not rebuild when the prelude changes #7077
Description
Expected Behavior
When using (mdx (preludes prelude.ml) ...), changing prelude.ml should cause the tests to be run again.
Actual Behavior
It ignores this and you have to do dune clean first.
Reproduction
$ ls
dune dune-project prelude.ml README.md
$ cat dune
(mdx
(preludes prelude.ml)
(files README.md))
$ cat dune-project
(lang dune 3.6)
(using mdx 0.3)
$ cat prelude.ml
let foo () = 1
$ cat README.md
```ocaml
# foo();;
- : int = 1
$ dune runtest
$ echo 'let foo () = 2' > prelude.ml
$ dune runtest
$ dune clean; dune runtest
