Update enshrined/svg-sanitize

Hi @fathershawn, thanks for your patch.

Could you create a MR please?

FYI because the module's composer constraints allow individual site maintainers to upgrade their site to a secure version of the dependency (enshrined/svg-sanitize) it fits within the jurisdiction of PSA-2011-002 → so no advisory is needed for this. That said, I've tagged this as a "security improvement" as it is important to encourage site owners to upgrade, and many won't until their modules require it.

There you go!

Merged. Thanks!
