^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}

keep draft until gdal recipe is updated.

freetype/2.12.1' requires 'libpng/1.6.39' while 'gdal/3.4.3' requires 'libpng/1.6.37'.
