feature: resize image in markdown

[creatxrgithub]

to limit image size in markdown document, eg:

![image134|10x10,1%](example.svg)
![image134](example.svg){width:10px, height:10px}

Abricotine only supports GFM (GitHub Flavored Markdown) which unfortunately does not include any size attributes for images. You can use the <img> tag as an alternative.

I've tried.

e.g.

![](example.svg)

It works in Abricotine.

https://github.github.com/gfm/#example-484

<img src="example.svg" style="height: 10px; width:10px;"/>
*<img src="example.svg" style="height: 10px; width:10px;"/>

It works in Github, but not in Abricotine. It shows the code text.
