Override templates names displayed in new page form

I need to override templates names displayed in “new page” form.
Does anyone know the proper way to do that?

I found it by myself. Imagine you want to override the template name “Default” in the new page form, you just have to create a translation file in yaml having a key “Default” (don’t forget to upper the first letter).
For example:

// Location: /user/themes/custom/languages/fr.yaml 
Default: Page de contenu

You will now see “Page de contenu” and not “Default” in your select box anymore.
