Update golangci format.outputs to stdout

The previous format.outputs give the following error in CI:

```
 * 'output.formats' expected a map, got 'slice'
  The command is terminated due to an error: can't load config: can't unmarshal config by viper (flags, file): 1 error(s) decoding:

  * 'output.formats' expected a map, got 'slice'
```

Change it to only output text to stdout with color turned on.
