Support unicode for Windows

[jeffsee55]

Windows supports unicode characters but the figures library that determines this is outdated. I suspect this is intentional because later versions of figures only support ESM.

It would be nice if Windows users got unicode, though I'm not sure what the best path forward would be if dropping CJS support is not an option.

I'm not against dropping figures and/or inlining core content of the library.

[jeffsee55]

Great, I'm happy to take a stab at it. Would you prefer to inline it into it's own package within the monorepo or just put it into @inquirer/core?

[SBoudrias]

It's own package, like @inquirer/figures (basically a simple fork to support cjs), would be best.

If we didn't use figures in multiple packages, then I'd prefer to inline it in those packages. But that'd be a lot of noise today since it's used often.
