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, whilecreate-next-app usesprompts)

The color library is changed topicocolors. IMOkleur is still the smaller library because of treeshaking. But@clack/prompts already comes withpicocolors as a dependency, so by not addingkleur, 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 theisCancel condition; update theneedsEslint type, etc.)
• I think we should remove thepackageName related logic but it can be postponed into another PR
• Get the message translations reviewed
