Get (most recent) mday of the backlinked notes of backlinked notes

Apparently I am not allowed to edit my post.
I got it one step closer:

```dataviewjs
for (const page of dv.pages('"Dossiers"')
	.where(page => page.file.path != dv.current().file.path)) {
	for (const inlink of page.file.inlinks) {
		dv.paragraph( page.file.name + "->" + dv.page(inlink).file.mday );
	}
}
```
