Remove vite-plugin-top-level-await plugin

[farmaazon]

Pull Request Description

We've used the vite-plugin-top-level-await to support top level await. But most of them were removed anyway, because the ide-desktop/lib/client is bundled as CJS and use some of gui2 code. And the plugin is causing problems, also in our CI
