feat!: v2

[caarlos0]

• updates everything to v2
• spinner is not its own module anymore - it had little reason to, IMHO - I also propose we move it into the root huh package btw
• spinner examples moved into ./examples
• renamed some of the spinner methods to be more similar to the rest of huh
• styling spinner the same way we do the rest (themes, dark mode, etc)

is it possible that the rationale behind spinner being in its own package was to have a standalone spinner that's possibly easier to set up than the bubbles spinner without needing to import the whole huh module? 🤔

Slight change to outputs
(this terminal emulator is showing padding with the teal underline). I added a Log statement to see the ansi and here's what it showed:
huh_test.go:1418: "\x1b[1;38;2;90;86;224mPassword:\x1b[m\u00a0\n"

Seems the space after the field title has been removed or is now styled whitespace instead.

[bashbunni]

I just removed the unstyled whitespace from the test cases, so they now pass. We can either do that or strip ansi before comparing got & want. Up to you on what you'd prefer :)
