[python] Bump macOS deployment to 10.15

Fix a problem when bumping to newer macOS runners. The minimum macOS deployment target to support `std::filesystem` is 10.15. (This also happens to cover all C++17 features that are listed on Apple's website [[1]].) This should allow us to use newer GitHub macOS runners (13+) without issue.
