Icons packaging: lacking `viewBox` and hardcoded `fill` color

[cyyynthia]

Hi!

First off thanks for your hard work building this cool icon pack :D - While adding it to my project, I noticed 2 problems that makes using them a bit annoying/difficult:

• They lack viewBox="0 0 24 24", making browsers misbehave when rendering them
• The use of a set color is always a bit of a bummer, it's always easier when icons support currentColor out of the box for use on the web

In my case I use https://github.com/cyyynthia/vite-plugin-magical-svg which generates a spritesheet and references symbols with use. It'd be great if the icons could be behaving nicely for these use cases.
