Update the images shown on "Drupal core release cycle: major, minor, and patch releases"

Problem/Motivation

The Drupal core release cycle page contains images showing dates and versions that are not kept up-to-date. Currently they are at least 4 years out-of-date, showing dates and versions for Drupal 8.5, 8.6 and 8.7, which all went end-of-life some time ago.

The first image shows the 6-month release schedule for Drupal core:

The second image shows the Minor release development and preparation schedule for Drupal core:

Proposed resolution

Can we come up with a plan that would ensure these helpful images were kept up-to-date with the current and future release schedule, at least within the currently supported (i.e., security team coverage) Drupal versions?

These images are helpful tools to visualise the release cycle. They are often cited when communicating to decision makers. Showing a schedule image that is approaching 5 years out-of-date does not inspire confidence and does not help the community.
