ci: remove broken semantic version check workflow

[Vinai]

The decision has been made to disable the workflow until we have the resources to fork and fix the project, and decide to do so.

Description (*)

The workflow currently seems to be broken. Example from github.com/mage-os/mageos-magento2/actions/runs/6424122506/job/17444076317?pr=22:
