Remove `pallet-getter` usage from pallet-transaction-payment (#4970)
As per #3326, removes usage of the `pallet::getter` macro from the `transaction-payment` pallet. The syntax `StorageItem::<T, I>::get()` should be used instead. Also, adds public functions for compatibility. NOTE: The `Releases` enum has been made public to transition `StorageVersion` from `pub(super) type` to `pub type`. cc @muraca polkadot address: 5GsLutpKjbzsbTphebs9Uy4YK6gTN47MAaz6njPktidjR5cp --------- Signed-off-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: Bastian Köcher <[email protected]> Co-authored-by: Oliver Tale-Yazdi <[email protected]>
