py-torch-spline-conv: add v1.2.2

[adamjstewart]

1.2.0 is failing in CI on aarch64, trying a newer version: https://gitlab.spack.io/spack/spack/-/jobs/11025715

Hi @adamjstewart! I noticed that the following package(s) don't yet have maintainers:

• py-torch-spline-conv

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("adamjstewart")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame py-torch-spline-conv

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.

Confirmed the two affected version sha256s.

Looks like py-torch-spline-conv's build is failing in CI.

Ah, didn't realize it's actually needed. See #43962.
