Update to newer version of TimelineJS
The TimelineJS verson used is currently at 3.6.5 https://github.com/ProfessionalWiki/ModernTimeline/blob/master/resources/vendor/timeline.js while the original repo is on version 3.9.0 ](https://github.com/NUKnightLab/TimelineJS3/blob/master/CHANGELOG.md)
At some point we should update to a more recent version,
There is a security issue on timeline.js 3.6.5 (CVE-2020-15092) so it would be better to update the library as soon as possible. We searched with @NavidBoy (apprentice at Wiki Valley) the new version of the library but we didn’t find in the same distribution form (1 JS file bundling multiple libraries). @JeroenDeDauw : do you know where to find this or how to compile it?
From what I understand, the issue is mostly related to using Google Docs. One would have to put malicious content in the wiki in order to exploit this, so I guess it is not a big problem for this extension.
But anyway it would be great to update the library.
Maybe also this helps: https://github.com/NUKnightLab/TimelineJS-Wordpress-Plugin
Digging deeper, I found this doc, and the compiled versions are explained here, so the new compiled version is downloadable here. It is now minified (at the contrary of 3.6.5).
Correct link: https://cdn.knightlab.com/libs/timeline3/3.9.2/timeline3.zip
PR with new version welcome. Good to test the extension after upgrading the lib, since they might have made breaking changes.
