[migration] Drop cubicweb-pyramid CWProperty in 3.24.0 migration This does a partial "drop_cube('pyramid')" equivalent but only considering CWProperty. We cannot just drop the cube since we have introduced some mechanism to exclude pyramid cube from config's cubes list and that would make MigrationHelper.cmd_drop_cube() call not return "pyramid" cube. Related to #14023058.

# Check the CW versions and add the entity only if needed ?
add_entity_type('CWSession')
rql('DELETE CWProperty X WHERE X pkey "system.version.pyramid"',
