Fix: Skip hidden inputs before text instance (#27358)

Found a hydration bug that happens when you pass a Server Action to
`formAction` and the next node is a text instance.

The HTML generated by Fizz is something like this:

```html
<button name="$ACTION_REF_5" formAction="" formEncType="multipart/form-data" formMethod="POST">
  <input type="hidden" name="$ACTION_5:0" value="..."/>
  <input type="hidden" name="$ACTION_5:1" value="..."/>
  <input type="hidden" name="$ACTION_KEY" value="..."/>Count: <!-- -->0
</button>
```

Fiber is supposed to skip over the extra hidden inputs, but it doesn't
handle this correctly if the next expected node isn't a host instance.
In this case, it's a text instance.

Not sure if the proper fix is to change the HTML that is generated, or
to change the hydration logic, but in this PR I've done the latter.
