Consider running with fixes explicitly disabled

### Welcome - [x] Yes, I understand that the GitHub action repository is not the repository of golangci-lint itself. - [x] Yes, I've searched similar issues on GitHub and didn't find any. ### Your feature request related to a problem? Please describe. If the golangci-lint config to be used specifies `fix: true`, the action will exit with success and no output besides "0 issues" in case golangci-lint managed to autofix all its findings. ### Describe the solution you'd like. The action should disable fix mode explicitly. This should be easily doable by defaulting `args` to `--fix=false`. It would be a bit of an annoyance for setups that pass other options in args as they would have to remember to include --fix=false in the ones they pass. So changing the default would not help them to avoid inadvertent successes. This would be a breaking change in a sense. ### Describe alternatives you've considered. Documenting the issue and the workaround. ### Additional context. Example affected repo and the workaround for it in https://github.com/home-assistant/cli/pull/633
