Upgrade to fabric 6 (#29334)

Browse source 
Upgrade fabric to latest v6 beta. It works for our use case, even
thought it does not fix the upstream issue
https://github.com/fabricjs/fabric.js/issues/9679 that
https://github.com/go-gitea/gitea/issues/29326 relates to.

(cherry picked from commit c4b0cb4d0d527793296cf801e611f77666f86551)

Conflicts:
	public/assets/img/favicon.svg
