chore(cmd): Refactor commit message language and model handling

- Add `commitLang` and `commitModel` variables
- Replace `commitCmd.PersistentFlags().StringP` with `commitCmd.PersistentFlags().StringVar`
- Remove `commit.lang` and `commit.model` bindings
- Use `prompt.GetLanguage` to check for default language
- Use `openai.GetModel` to check for default model
- Remove `color.Green("Summarize the commit message use " + viper.GetString("openai.model") + " model")` from line 49
- Set `viper.Set("output.lang", commitLang)` if `prompt.GetLanguage(commitLang) != prompt.DefaultLanguage`
- Add `color.Green("Summarize the commit message use " + viper.GetString("openai.model") + " model")` to line 81
- Add error handling for translation in the `if` statement in lines 87-96
