Use colors in tab-completion in PyREPL #130472
Description
The current tab-completer is somewhat basic. There's a pyrepl-based library called fancycompleter that allows for context-aware colorful tab completions. Much more useful and looks better.

I actually have a question about the overall color-related features - how many colors can we use at this point, and how should we use them? If I remember correctly, it took a while to land on this magenda color for some stuff, and we are planning to add much more colors for completion? How much we need to think about for color-blindness or different terminal backgrounds to use new colors? I always have this question because pdb could really use some colors, but it doesn't seem like we have a consensus about how we can use them.

@gaogaotiantian the plan is to add theming support in PYTHONSTARTUP. I'll be working on this in March.

This introduced some regressions:

No blinking here, but
webbrowser.GenericBrowseris not visible:And the strikethrough, italic, underline and dimmed text is surprising.

I found the root cause for some issues, though contrast issues remain: https://github.com/python/cpython/pull/130473/changes#r3038878981

I think #148161 should do the trick

If it's ok, I'll reopen this for #148188 since it's related (I can also open a separate issue if you prefer though)
