Add icon and padding

[NoAccount1]

Hello, small pull request to add a favicon to the extension.

I also added space padding for userscript metadata. I can remove it if you don't like it

Hey, thanks for the PR, I appreciate the interest.
The icon is nice, but I don't really see what it brings to the table. (Visibility in userscript managers amidst other scripts, not sure if very useful in practice?)

Linking their image as an icon seems like potential grounds for a takedown (I assume it's not valid reasoning but I'm not interested in going through that path), whilst not really providing much value.

I'm not that strongly against nor in favor of the addition. Do you have a reason in mind to add the icon, which would improve user experience?
Cheers (sorry for putting such a simple change through this)

This is honestly mainly about aesthetics
I just like having a list of userscripts with their respective icons while it also helps navigating it.

If you prefer not adding it, that's fine 😅
I can also provide a base64 encoded image without link to the website if you prefer
