refactor(update): remove use of @std/fmt/colors

[iuioiua]

This module simply isn't needed as console methods support CSS styles natively.

This breaks color output in macOS' built-in Terminal app. That one famously doesn't support 16bit truecolor and only up to ansi256.

import * as colors from "jsr:@std/fmt/colors";

console.log("Before:");
console.log(colors.bgRgb8(
  colors.rgb8(" 🍋 Fresh Updater ", 0),
  121,
));
console.log();
console.log("With this PR:");
console.log("%c 🍋 Fresh Updater ", "background-color: #87ffaf; color: black;");

Ah, yes, that's right! In that case, I'd almost go as far as to say that any background styling in console methods should be recommended against. Does denoland/deno#18549 or denoland/deno#28122 fix this issue?

[marvinhagemeister]

Yeah the first one would fix it. We don't have any code in the console at the moment to convert from 16bit colors to ansi256.

I've done no prior reading on how it all works, so I have essentially zero context. It'd be great if we can re-open and complete that PR. From what I remember, tests were all that remain. Is that correct? Fixing that would also help fix https://github.com/denoland/std/blob/6a00d6cd34ca70b3a38932e313151a80531c5d2b/internal/build_message.ts#L29.
