feature: github image (link)

[fredrikaverpil]

Did you check the docs?

• [x] I have read all the snacks.nvim docs

Is your feature request related to a problem? Please describe.

I think it would be awesome if the snacks image plugin could handle github image links out of the box. Example:

# 🍿 image

![Image](https://github.com/user-attachments/assets/4e8a686c-bf41-4989-9d74-1641ecf2835f)

Describe the solution you'd like

Just some sort of built-in, zeroconfig, support.

Describe alternatives you've considered

I guess a custom resolver is required, but it would be cool not to have to define it in my config.
