MTProto Update: gifted_premium.py argument mismatch

[msx98]

The generated raw.types.message_action_gift_premium (only visible after compilation) contains:

        currency (``str``):
            N/A

        amount (``int`` ``64-bit``):
            N/A

        days (``int`` ``32-bit``):
            N/A

        crypto_currency (``str``, *optional*):
            N/A

        crypto_amount (``int`` ``64-bit``, *optional*):
            N/A

        message (:obj:`TextWithEntities <pyrogram.raw.base.TextWithEntities>`, *optional*):
            N/A

As you'll notice it currently uses days not months
Kept month_count in case anyone is using it
