Pyinterp-feedstock pv313

Hello,

My pyinterp package has not yet received a migration file for Python 3.13, even though all dependencies are available. I created a migration file manually, and the builds are successful on all platforms except OSX/ARM64, where there’s a configuration error. I might have made a mistake in the creation process. Could you help me understand why the PR for Python 3.13 wasn’t created automatically and identify the source of my error? Thank you in advance!
