Revert Mainnet genesis file changes from #1535 (#1566)

## Description

The mainnet genesis file was changed as part of PR #1535 when adding misc changes for localnet. Since I believe the genesis file is generated anded loaded via `InitGenesis`  and `InitChainer`, this resulted in a different genesis from the rest of the network and ultimately a different generated app hash than what the other peers are synced to. As a result, this caused syncing issues when trying to produce the first block and onwards as reported in #1564.

This change reverts the changes made in the genesis json in #1535

Tested by applying this change and running 
```sh
pocket start --seeds="7c0d7ec36db6594c1ffaa99724e1f8300bbd52d0@seed1.mainnet.pokt.network:26662,cdcf936d70726dd724e0e6a8353d8e5ba5abdd20@seed2.mainnet.pokt.network:26663,74b4322a91c4a7f3e774648d0730c1e610494691@seed3.mainnet.pokt.network:26662,b3235089ff302c9615ba661e13e601d9d6265b15@seed4.mainnet.pokt.network:26663" --mainnet
```
