REST API: Use the `integer` type for `page_on_front` and `page_for_posts` options.

This adjusts the newly added options in the settings endpoint to use the `integer` type instead of `number`. Since these are page IDs and are not supposed to be floats, `integer` is the correct type.

Follow-up to [53588].

See #56058.
