Accept avatars in .svg format

[brobr]

Feature Description

Related to #24263, and initially raised for .webp format at Codeberg, also avatars in .svg format are not accepted/recognized as an image. It would be nice if that format gets accepted as well.

Thanks.

The problem is: While it might seem like exactly the same feature, it is completely different:
webp is a "normal" image that works with the <img> tag.
svgs however need their own tag (<svg>).
So, this would need a complete rewrite of the logic.
That is such a huge change that I don't think the benefit is worth the effort.
It's far easier to require users to convert their svgs beforehand.
So, from my side this is a weak reject.
I don't know how other maintainers see it.

I think you can do <img> with SVG https://caniuse.com/svg-img

Okay, TIL.
In that case, my comment above is now outdated and no longer a blocker.

Since JS code could be embedded in SVG, the security concern should be addressed first.

Duplicate with #8707. The challenge with SVG is security as SVGs can contain scripts so a proper sanitizer is needed. <img> tag will otherwise work fine.
