The Issue or Context

@BasPH Created a Python script to generate a Gantt chart of all Runtime, CLI, and Software releases so that customers can more easily parse which versions of the Software they can use with other Astro products (example). The chart is hugely helpful, but we need to implement the script on the docs site so that it stays up to date with the latest releases and timelines.

Fix or Proposed Change

Create two GitHub actions:

• An action that generates the Gantt chart weekly, in order to show an accurate current timeline
• An action that runs whenever a maintenance date is manually added/ updated by a docs team member. This workflow would become a regular process for new version updates.

The action would commit the mermaid gantt chart to a text file, which could then be loaded into the Version Compatibility reference pages as an element.
