Decrease Pool Creation fee to 400 OSMO

This proposal directly lowers the Pool Creation fee to 400 OSMO.

Background

Since the Pool Creation fee was increased in V19 to 1000 OSMO, very few new Supercharged pools have been created.

This may be due to the lack of User Interface for Supercharged pool creation, which currently requires CLI usage. The documentation for this is available here. However, very few Balancer or Stableswap pools have also been created in this time despite the availability of new assets such as USDC and USDT.

This proposal would lower the Creation fee to 400 OSMO (~$100 at time of writing).

This results in a slightly higher spend than before the change to minimise spam as was being discussed in this forum thread: https://forum.osmosis.zone/t/proposals-addressing-scam-pools-increase-the-pool-creation-fee/42

We are at a stage in Osmosis where new pools should be being made to find the optimal fee for a trade and this proposal asks that the financial barrier to this be reduced.
