When work with ruby 3.1.X, [looksee](https://github.com/oggy/looksee) gem could not display color character correct in new version IRB, as you can see as following:

```

reproduce process [here](https://github.com/oggy/looksee/issues/57#issuecomment-989731946)

But, it works before introduce the colorful feature of IRB, and work still quite well with Pry.

we can fix this issue use following workaround.

```rb
IRB.conf[:USE_COLORIZE] = false
```

But, that will make IRB lose colorful.

So, i thought somethings break changes introduced since new IRB released.

following is a screenshot, check how looks [here](https://github.com/oggy/looksee/issues/57#issuecomment-999771143)

I thought this issue should possible be fixed, so, i do some hack myself. 

if change https://github.com/ruby/ruby/blob/v3_1_2/lib/irb/context.rb#L56 line from
`@use_colorize = IRB.conf[:USE_COLORIZE]` into `@use_colorize = false`, it works perfect, 
that is, irb is colorful, and looksee output is colorful too.


But, above source code was moved on newest master, I am not sure if this issue was fixed in ruby 3.2.0 too.
because install ruby-head or 3.2.0-preview both failed on my laptop use RVM.

so just ask here.

thank you.
