Enhancement request: add support for hyperlinks in Timeline diagrams

[indexing]

I'm currently using the Timeline diagram to present our product roadmap by year and by quarter. Quarters in the diagram contain a set of initiatives. We manage each initiative using the milestones feature in Github.

I would like to provide more interactivity to my roadmap by providing links from each initiative in the Timeline to the relevant Github milestone, but the Timeline diagram type does not yet support hyperlinks.

better if we can support the [text](link) syntax
