  Renders a live component inside a modal.

  The rendered modal receives a `:return_to` option to properly update
  the URL when the modal is closed.

  ## Examples

      <.modal return_to={Routes.<%= schema.singular %>_index_path(Endpoint, :index)}>
        <.live_component
          module={<%= inspect context.web_module %>.<%= inspect Module.concat(schema.web_namespace, schema.alias) %>Live.FormComponent}
          id={@<%= schema.singular %>.id || :new}
          title={@page_title}
          action={@live_action}
          return_to={Routes.<%= schema.singular %>_index_path(Endpoint, :index)}
          <%= schema.singular %>: @<%= schema.singular %>
