PR Summary

• Optimization of drop_down_list_component.rb Method
  The contains_long_option? method will now utilize @champ.enabled_non_empty_options rather than @champ.options.

• Improvements in Dropdown Selection in drop_down_list_component.html.haml
  The textual content "Autre" has been replaced with t('shared.champs.drop_down_list.other'). Additionally, the render method for Dsfr::ComboboxComponent now factors in the other: true option in @champ.enabled_non_empty_options.

• Modification in combobox.ts Method
  The _render method will now invoke Action.Update when the combobox is left open.

• Code Cleanup in champ.rb, drop_down_list_champ.rb, and multiple_drop_down_list_champ.rb
  The options method has been eliminated from the mentioned files. The enabled_non_empty_options method can now handle the other parameter, which is a more efficient and flexible approach.

• Enhanced Routing Rule Evaluation in groupe_instructeur.rb
  The routing_rule_matches_tdc? method will now use the improved routing_tdc.drop_down_list_enabled_non_empty_options(other: true) instead of the old routing_tdc.options_with_drop_down_other.

• Improved Options Handling Method in champ_value.rb
  The method dealing with options will now use tdc.drop_down_list_enabled_non_empty_options(other: true) and is capable of handling both single and array values.

• Update to type_de_champ.rb Method
  The method drop_down_list_enabled_non_empty_options is now equipped to accept other parameters. The old options_with_drop_down_other method has been removed.

• Addition of New Translation for "Other" Option
  A new translation for the "Other" option, denoted by shared.champs.drop_down_list.other, was introduced in the locale files. This replaces the old label "Autre", enhancing the user interface across different languages.

OK (au passage j'ai vu un pb d'alignement du champ other qui n'a rien à voir avec cette PR que je vais corriger)
