upgrade to 47 or 50

[faddat]

summary

SDK 46 is sort of cancerous and you should avoid using it in the long run.

maintenance considerations

• 46 is no longer supported by the cosmos-sdk development team
• security patches and such for wasmd have never been released on the v0.46.x branch, it's a branch that Notional made, and in the long run I became dissatisfied with maintaining it because of the number of correctly diagnosed issues between the 46 series and cosmwasm
