(cibuildwheels needed upgrade because of CentOS 7 mirror EOL).
Fix was done by pinning delocate to 0.10.7.
The proposed version 0.11 had trouble with libpng on MacOS 13
Github runners. cibuildwheels does builds for the minimal
platform - 10.9 - and libpng was detected to need 13.0.
delocate 0.10.7 ignores library version requirements, hence did not have
this trouble.
