Better EventAttributes types

[dinfer]

What is the feature you are proposing?

<input
          placeholder="username"
          onChange={(e) => {
            model.username = e.target.value; // Property 'value' does not exist on type 'EventTarget'.ts(2339)
          }}
        />

Hi @dinfer

This is a good issue and is the same with honojs/hono#2491
