Add support for scikit-learn 1.5.0

[gsheni]

Problem Description

• Currently, we restrict scikit-learn <1.5 for python 3.10 and 3.11.
  • scikit-learn supports < 1.3.2 for python 3.8 and 3.9
• We would like to support the newest release of scikit-learn.

Expected behavior

• Copulas supports scikit-learn 1.50

Additional context

• Remove upper bound restriction in pyproject.toml
• Update any associated tests
