Remove the t name from the generated Go code

[a-h]

This won't compile:

{% templ Todo(t *todo.Todo) %}
  <div>
    <div>{%= t.Item %}</div>
  </div>
{% endtempl %}

Because there's already a (t templ.Component) return variable.

func Todo(t *todo.Todo) (t templ.Component) {
	return templ.ComponentFunc(func(ctx context.Context, w io.Writer) (err error) {
		_, err = io.WriteString(w, "<div>")
		if err != nil {
   ...

There just doesn't need to be.
