Editor: Replace a Gutenberg specific function with the Core equivalent.

This replaces a stray instance of `gutenberg_experimental_set()` with the WordPress Core version of this function, `_wp_array_set()`.

A stray `gutenberg` text domain is also removed from a `__()` call.

Props walbo, chaion07, JeffPaul.
Fixes #53369.
