fix: support language dynamic slug in OneNavigation

[syi0808]

Cause

The #228 issue was caused by one Navigation's link being fixed as a Korean link.
To fix this, I modified it so that It can put language dynamic plugs in the link.

📝 Key Changes

• Add language dynamic slug in ONE_NAVIGATION_ITEMS
• Create new navigationItems with dynamic slugs replaced

If we want to prevent human error with TypeScript out of necessity, we can do the following, but it seems to be too much for me personally.

type AllowedSlug = 'lang';

type ValidateDynamic<S extends string> =
  S extends `${infer _Start}{${infer Param}}${infer Rest}`
    ? Param extends AllowedSlug
      ? ValidateDynamic<Rest> extends never
        ? never
        : S
      : never
    : S;

export interface NavItem<H extends string = string> {
  path: string;
  href: ValidateDynamic<H>;
  tooltip: {
    ko: string;
    en: string;
  };
  icon: string;
}

function defineNavItem<H extends string>(
  item: Omit<NavItem<H>, 'href'> & { href: ValidateDynamic<H> }
) {
  return item as NavItem<H>;
}

const ONE_NAVIGATION_ITEMS: NavItem[] = [
  defineNavItem({
    ...
