25€ and upwards tiers secondary vote gets extra voting power

Just a small meta update rergarding Isekai Author+ tiers.

Since the number of people (like 5 people :'D) in these tiers is so small that they basically have no effects on the vote, the benefit of the secondary vote currently feels a bit useless. So, to bump it up a bit the voting power in the secondary vote will be considered with a multiplier of x25.

This way it won't completely overshadow the lower tier votes, but still have a significant impact.
