ibc-go v4.0.0

[faddat]

This PR riffs on these PR's:

• ibc-go v3.2.0 #937
• Upgrade ibc-go to v4.0.0-rc2 and go to 1.18 #919

To create a v0.45.7 wasmd that also uses ibc-go v4.0.0 and would be most suited to Juno's v10 upgrade.

Thanks to David, author of #919

Note: if we merge this, then #937 should be closed. This is my preference for merging, so I've updated it, but please let me know if there's a preference for #937. Thanks!

Update

Since main is updated to v45.7, this branch now serves only as an upgrade to ibc-go v4.0.0

It also changes the version of golangci-lint from v1.47.0 to v1.47 so that we catch all go 1.18 compatible updates in golangci-lint (eg 1.47.*)

Thanks a lot for this PR and showcasing the upgrade! 💪
I have not looked at the code yet but instead created #960 to discuss and track the ibc v4 upgrade and to get timing right.

We should not do this.

@faddat why not?
