refactor!: autocli go.mod and package naming

[aaronc]

Description

Ref #11775

This moves:

• github.com/cosmos/cosmos-sdk/client/v2 -> cosmossdk.io/client/v2 (we need vanity URL updates for this)
• github.com/cosmos/cosmos-sdk/client/v2/cli -> cosmossdk.io/client/v2/autocli since autocli seems better
