Put imports inside declaration (outside namespace)

[vixalien]

Otherwise it generates code like this

/// <reference lib="es2015.iterable" />
/// <reference path="./gobject2.d.ts" />
/// <reference path="./glib2.d.ts" />

/**
 * Gio 2.0
 *
 * Generated from 2.77.0
 */

declare module "gi://Gio?version=2.0" {
    namespace Gio2 {
        import GObject from ["gi://GObject?version=2.0"](gi://GObject?version=2.0);
        import GLib from ["gi://GLib?version=2.0"](gi://GLib?version=2.0);

        export namespace BusType {
            export const $gtype: GObject.GT

which throws errors:

 Error: Import declarations in a namespace cannot reference a module.ts(1147)

Solved by putting imports inside module declaration, but outside of namespace like so

/// <reference lib="es2015.iterable" />
/// <reference path="./gobject2.d.ts" />
/// <reference path="./glib2.d.ts" />

/**
 * Gio 2.0
 *
 * Generated from 2.77.0
 */

declare module "gi://Gio?version=2.0" {
    import GObject from ["gi://GObject?version=2.0"](gi://GObject?version=2.0);
    import GLib from ["gi://GLib?version=2.0"](gi://GLib?version=2.0);
    
    namespace Gio2 {
        export namespace BusType {
            export const $gtype: GObject.GType<BusType>;
        }
