chore: update and streamline linting configuration and error formatting

- Update `.golangci.yaml` to version 2 and streamline settings
- Remove specific linters from `.golangci.yaml` configuration
- Add exclusion and formatter settings to `.golangci.yaml`
- Change error message formatting in `plugin.go` to lowercase
- Use `strings.ReplaceAll` instead of `strings.Replace` for better readability and performance in `plugin.go` and `plugin_test.go`
