Unable to use top level await in projects

[Artur-]

Description of the bug

According to https:/vaadin/platform/releases/tag/24.0.0 24.x supports Safari 15.4+ and evergreen versions of all other browsers. All of these support top level await but if you try to use it in a project, you get

VAADIN/build/indexhtml-!~{001}~.js:5066:27: ERROR: Top-level await is not available in the configured target environment ("chrome87", "edge88", "es2020", "firefox78", "safari14" + 2 overrides)

The target environment seems a bit off, with the wrong safari major and old versions of all the other browsers

Expected behavior

You can use top level await.

Like you can today by manually adding

  build: {
    target: ["esnext", "safari15"],
  },

to vite.config.ts

Minimal reproducible example

Create a new project, add e.g.

await import("./other.js");

in index.js
