Update ibc-go to v4

[ulbqb]

Description

This PR updates ibc-go to v4 along with wasmd.

According to v3 to v4 migration guide, there is nothing to handle.

• ICS27 - Interchain Accounts - Finschia doesn't have ICA controller.
• ICS29 - Fee Middleware - Finschia doesn't have 29-fee.
• Migration to fix support for base denoms with slashes - This is needed only when updating ibc-go from v3.1.0 or below to over. See support denoms with slashes.
