Increase the Stargaze active validator set from 120 to 130

This is a proposal for us to increase our active set of Stargaze validators from 120 to 130.

If this proposal passes, the active set will increase and we will welcome up to 10 additional validator operators.

Why? To continue to lower the entry barrier for new Stargaze validator operators. StargazeProp36 (https://www.stargaze.zone/vote/36) had only 4% voting against (vs 90% voting yes)

Why not? Increasing the set of a Cosmos chain can cause block time increases, but Jorge has indicated that this increase should not cause performance issues: https://discord.com/channels/755548171941445642/755548171941445645/1019722347839766579. I've seen criticism relating to economic difficulty for newcomers to sustain their validator operations.

Regardless, I think that it's worth expanding the set to enable alexandr0 and other, lower-ranked inactive validators to resume operating on our network.
