chore: add OpenAI configuration options to commit command

[appleboy]

• Add openai.WithTopP(float32(viper.GetFloat64("openai.top_p"))) to commit.go
• Add openai.WithFrequencyPenalty(float32(viper.GetFloat64("openai.frequency_penalty"))) to commit.go
• Add openai.WithPresencePenalty(float32(viper.GetFloat64("openai.presence_penalty"))) to commit.go
• Add openai.top_p to availableKeys in config.go
• Add openai.frequency_penalty to availableKeys in config.go
• Add openai.presence_penalty to availableKeys in config.go
• Add configCmd.PersistentFlags().Float32P("top_p", "", 1.0, "An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.") to config.go
• Add configCmd.PersistentFlags().Float32P("frequency_penalty", "", 0.0, "Number between 0.0 and 1.0 that penalizes new tokens based on their existing frequency in the text so far. Decreases the model's likelihood to repeat the same line verbatim.") to config.go
• Add `configCmd.PersistentFlags().Float32P("presence_penalty", "", 0
