Modernizes the approach to golangci:

• use gofumpt instead of gofmt and goimports
• run golangci-lint run ./... --fix
• run find . -name '*.go' -type f -not -path "*.git*" -not -name '*.pb.go' -not -name '*pb_test.go' | xargs gofumpt -w -l
• pairs nicely with
  • do not use ioutil #9206
  • update ci to go 1.19 #9205
  • goimports, gofmt -> gofumpt #9207

But it seems that make proto-gen is broken

In cosmos, intermittent test failures are common. I thought this came from the sdk, but maybe it's coming from tendermint, as I've seen a few tonight.

2nd thought on the test failures: I guess building the sdk doesn't run the same tests? This is a high-value mystery imo

3rd thought: we've got intermittent test failures in this repo, proof:

e25196d

5d6da11

...should not have different test outcomes.

note about these pr's

They're basically remote-diagnosis of the ci system, which is why there's many of them, they touch many files, and they're similar.

Fairly sure at this point that we've got an intermittent test failure that we can just step aside by tossing in an additional commit.

PR checklist

• Tests written/updated, or no tests needed
• CHANGELOG_PENDING.md updated, or no changelog entry needed
• Updated relevant documentation (docs/) and code comments, or no
  documentation updates needed
