feat: add web template

closes #89

This can be improved by using a App struct and so on, but I'm okay with this structure as well. Just LMK!

I think this one probably belongs in its own repo (or possibly the ratzilla main repo?)

[orhun]

Sure, but wouldn't it be nice to allow bootstrapping different kinds of application with a single cargo generate command?

Are you concerned about the maintainability of the code because of 3rd party libraries?

No, it's mostly that ratzilla is a bit more niche than ratatui, and I think it's worth giving it a bit of room to grow and gain some adoption. Giving this its own repo allows the sorts of web apps that you might be able to build grow over time, and it also makes it easy to have that follow the ratzilla development more closely as you discover new approaches to things.

[orhun]

Sure, sounds reasonable.

Added to the main repo in ratatui/ratzilla#62
