This update simplifies the l10n_cz and l10n_sk modules by removing a previously added field for taxable supply rates. Now, the system utilizes the existing delivery date information instead, streamlining data management. This change improves efficiency and reduces potential complexity.

A field taxable_supply_rate was added for both l10n_cz and l10n_sk modules before as delivery_date didn't exist back then. Now, we can remove the field and use delivery_data in its place.
