Add a version constraint to the launch script

Closes #3496758

This seems fine. Tested with v1.23.5:

failed to validate config: unable to start the 'gjunk' project: your DDEV version 'v1.23.5' doesn't meet the constraint '>=1.24.0'. Please update to a DDEV version that meets this constraint or update the ddev_version_constraint in your .ddev/config.yaml file

Tested with v1.22.7:

failed to validate config: the gjunk project has a DDEV version constraint of '>=1.24.0' and the version of DDEV you are using ('v1.22.7') does not meet the constraint. Please update the ddev_version_constraint in your .ddev/config.yaml or use a version of DDEV that meets the constraint

With v1.21.6 it gets: Error: unknown flag: --ddev-version-constraint

Looks good with manual testing.
