fix: Downgrade and replace Tendermint verison to Informal/tendermint v0.34

[mattverse]

What is the purpose of the change

Current Osmosis(https://github.com/osmosis-labs/osmosis) tendermint dependency is using informal / tendermint with the verison of v0.34 (https://github.com/osmosis-labs/osmosis/blob/main/go.mod#L320).

Instead of using dependencies from two different sources, we should change this so that we use the same tendermint version for the two different repositories(sdk and osmosis).

Seems like tendermint version was bumped to v0.37 in a PR of ABCI 1.0 integration, (https://github.com/osmosis-labs/cosmos-sdk/pull/345/files) upon CI passing it should be safe to down grade and replace the tendermint dependecy used here to informal tendermint 0.34

Brief Changelog

• Downgrade and replace Tendermint version to Informal/tendermint v0.34
