Remove dependency on deprecated oldest-supported-numpy

[mathiasburger]

Change Description

Remove dependency on the deprecated oldest-supported-numpy. They state that it is not necessary to use that package anymore since numpy 1.25. To my understanding, the dependency would only be required as build-time-dependency and not as a runtime dependency.

Issue reference

The dependency breaks resolution for artifacts requiring a higher version of numpy:

File "/opt/python/versions/3.11.10/lib/python3.11/site-packages/resolvelib/resolvers.py", line 318, in _backjump raise ResolutionImpossible(causes) resolvelib.resolvers.ResolutionImpossible: [RequirementInformation(requirement=<Requirement('numpy==1.26.4; python_version >= "3.11" and python_version < "3.12"')>, parent=None), ..., RequirementInformation(requirement=<Requirement('numpy==1.23.2; python_version == "3.11" and platform_python_implementation != "PyPy"')>, parent=Candidate(name='oldest-supported-numpy', version=<Version('2022.11.19')>, extras=set()))]
