[CI] fix:* commands are failing because they can't pickup the latest docsy submodule

For example:

• https://github.com/open-telemetry/opentelemetry.io/actions/runs/7919760669/job/21621259150

Fixed: I had not pushed the new tag to the cncf/docsy repo. I'm going to keep this open until I find a way to automate it or document the requirement (that tags be pushed).
