Gnatt - Recurring milestones/items

[andyatcd]

Is your feature request related to a problem? Please describe.
Showing repeating milestones for the same thing in gnatt charts takes up lots of vertical space

Describe the solution you'd like

I'd like to be able to illustrate regular project governance meetings as milestones with a recurrence pattern of 'n' -

e.g.
Sprint Demo : milestone, sd, 01-Mar-2025, repeats 2w

This would draw multiple milestone blocks on the same line for the 'Sprint Demo' item.

Describe alternatives you've considered
I tried repeating the same item but it takes up vertical space. I ended up taking my 'Project Governance' section out of the mermaid gnatt chart altogether.
