fix:Changes comment in layout template (#1736)

* Changes comment in layout template

This change updates the comment in the layout template, which is visible to developers. It changes the word "callback" to "script", which helps us to avoid referencing a nonexistent callback for scenarios that don't use them.

* fix: Adds a random commit that is semantic

Forgot to put on my semantic hat again today.
