feat!: use a giant multiselect instead of individual toggles for features

[haoqunjiang]

As we are adding more features, the number of toggles is getting out of hand. A multiselect could save a few keystrokes for most users.

I also take this opportunity to change the prompts library to @clack/prompts.
(For context: create-astro, sv, create-preact, create-solid, create-qwik all use @clack/prompts, create-vite recently switched to @clack/prompts too, while create-next-app uses prompts)

The color library is changed to picocolors. IMO kleur is still the smaller library because of treeshaking. But @clack/prompts already comes with picocolors as a dependency, so by not adding kleur, we save a few bytes.

This is a proof-of-concept PR. I haven't put much consideration into the code style yet. Nor have I updated the i18n messages. I will do that if this change is accepted.

See the result in a screen recording:

TODOs:

• Clean up the code (wrap the isCancel condition; update the needsEslint type, etc.)
• I think we should remove the packageName related logic but it can be postponed into another PR
• Get the message translations reviewed

Looks good, I like the idea 👍

I think this PR is ready for review. I can confirm the flags parsing behavior is exactly same, but I can only manually test the prompt parsing, so far it seems good.

@cexbrayat @btea Do the new prompt messages look good to you?
If so, would you please help review the French translation of the new messages @cexbrayat ? They were translated by Claude 3.5 Sonnet, I'm not sure if I can trust it.

LGTM

Merging this PR now as I'm going to do another round of dependency maintenance and release a new version tomorrow.
