add array_interpolate_linear process

docs: https://docs.openeo.cloud/processes/?#array_interpolate_linear

A return type in the docs is number|null but there is nothing about propagating null if the array is null or empty (like for some of the other processes). So, I'm not sure.

I think the return type should be array<number|null>. For empty array I'd assume empty array is returned, for null probably null. Perhaps open an issue for that in openeo-processes repo

Nothing to change as it already behaves as it should.
