Add pre-commit hook to run config verify

Add this as a way to easily ensure configs stay valid. Filenames are not
passed to the hook, this means For the default case (config in one of
the default searched files), the config is picked up automatically and
there's nothing extra to configure. For the case of a non-standard
config setup the hook can be configured like

    repos:
    -   repo: https://github.com/golangci/golangci-lint
        rev: v1.57.2
        hooks:
        -   id: golangci-lint-config-verify
            # config is kept at '.golangci-config.yaml'
            files: \.golangci-config\.yaml
            args: ['--config', '.golangci-config.yaml']
