chore: lint tests

[faddat]

Lint tests so that the codebase is consistently linted

• bump golangci-lint
• lint tests
• add gci linter
• enable errcheck linter

[faddat]

gci is that linter, and it is configured in its standard way.

We could also configure it to group like how was done in ibc, or sdk.

Ah, yeah I think I know exactly what you're looking for after checking the changeset.... moment

[faddat]

@julienrbrt I think that checking errors found a bug. To make this easier to review, I'll separate the gci changes.

@Pantani - actually that makes sense! Let me fix that issue with the import ordering.

Thanks for pointing it out.

[faddat]

recommend merging this first:

• https://github.com/ignite/cli/pull/4162

[Pantani]

@faddat, there are some merge conflicts. I think the problem is because the cleanup method into the cosmosbuf pkg was removed
