This update adds an intelligent auto-complete widget for HSN (Harmonized System of Nomenclature) codes in the India localization module. When users enter product information, the system now suggests matching HSN codes and automatically fills in the corresponding description, making data entry faster and more accurate for Indian businesses.

- In this PR, we make some requests in js to get a list of HSN codes to
  match with the input entered by the user in the field.

- And for the options attribute in hsn_autocomplete widget, when a user selects
  an option from the list, the hsn_decription will be stored in the field
  specified by the user.
