  Extends `Phoenix.Component.form/1` options to merge css class as with
  `PhxComponentHelpers.extend_class/2`.

  It's useful to define your own `my_form` function with default css classes that still can be
  overriden from the template.

  ## Example
  ```
  def my_form(options) do
    new_options = extend_form_class(options, "mt-4 space-y-2")
    Component.form(new_options)
  end
  ```

  end

  def extend_form_class(options, default_classes) when is_map(options) do
