Gorm Allow Logger.Config.Colorful to be set as needed

Describe the feature

I was looking to a have Method (example: func (l *logger) ColorMode(enabled bool) Interface that allows the Logger colors to be set after the logger has been initialized

https://github.com/go-gorm/gorm/blob/1e8baf545953dd58e2f301f4dfef5febbc12da0f/logger/logger.go#L91-L120

Motivation

I've had this use case where at times when I use the default logger, it has the Colorful option set to true, and while it's great for most cases, there are times where I'll be outputting the logs to a random file, but it shows all the control characters with it which ends up getting a bit muddy. Seems like the only way to have this configured is by creating a new instance of the logger with the Config.Colorful = false.

Reading through the code, seems like there is a possibility to ensure that the default config is always respected, and the user can also disable the logger colors if needed

This is what I had in mind, and if it looks okay, happy to open a PR for it, (although not sure what the best way for testing out the logger is in this repo)
