chore: Upgrade the Cosmos-SDK to Go 1.18

[faddat]

Description

This PR works towards the completion of the Go Workspaces issue #11450

It does the following:

• Upgrades the Cosmos-SDK to Go v1.18
• Changes the version of gogo/protobuf to v1.3.2, which exists upstream, unlike v1.3.3 everywhere possible. The use of the 1.3.3 version number and lack of an upstream version is the blocker for Go Workspaces.

PS: The reason that I took the explicit versions out of the Dockerfiles is that if they are there, it is certain that:

• They'll need to be updated in the future
• we'll be using out of date builds of alpine

By not specifying the versions explicitly, we will always use the latest Go and alpine

@faddat there are two CI failures

• For runsim, we need to tweak how it gets the dep -> https://github.com/cosmos/cosmos-sdk/runs/6078402965?check_suite_focus=true

• For rosetta, I'm not too sure -> https://github.com/cosmos/cosmos-sdk/runs/6078351628?check_suite_focus=true

I think it is super reasonable to mention:
