Add a "scroll to position" function

I was looking at implementing some editor commands that scroll to next function/method/thing and none of the current API's scroll. Looks like there was a change at some point that made insert text, set selection, etc not scroll by default in VSCode.

We should implement a new request ShowEditorPositionRequest and add a function (Show-EditorPosition?) to Commands that sends it (and optionally also add it to $psEditor)

The VSCode implementation could use the TextEditor.revealRange method.

Commencez par retracer comment Commands envoie les requêtes de l’éditeur et comment l’implémentation de VSCode gère les opérations de l’éditeur. Examinez la proposition ShowEditorPositionRequest, la commande Show-EditorPosition et l’API facultative $psEditor, puis comparez la documentation de VSCode TextEditor.revealRange. Le travail est considéré comme terminé lorsque la requête et la commande peuvent afficher la position demandée dans l’éditeur de VSCode.
