Fix vtk941.yml migration extension and add run dependencies to ensure find_package(PCL) is successful

[traversaro]

#79 contained an error, as the vtk941 migration file was named .ci_support/migrations/vtk941.yml instead of .ci_support/migrations/vtk941.yaml (the difference is in the yml extension that must be yaml.

I also added a check on find_package(PCL) working correctly to the CI that it would have catched the issue if present.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

It seems that find_package(VTK) fails if one just depends on vtk with vtk 9.4.1, I guess we need to bring this back to the vtk feedstock.

Ok, I think to avoid being blocked we can add the required run dependencies to ensure that find_package(PCL) here, see RoboStack/robostack.github.io#65 (comment) .

ppc64le is failing I guess due to the failure in conda-forge/vtk-feedstock#373 (comment) .

There are still failures like:

-- Could NOT find LZMA (missing: LZMA_LIBRARY LZMA_INCLUDE_DIR) 
-- Could not find the VTK package due to a missing dependency: LZMA

let's just wait for conda-forge/vtk-feedstock#375 .

The pcl conda package is incompatible with icu >=75.1, which is needed to install libgdal=3.11.0 on Mac Arm.

I am not sure if that is related to the vtk error here, but in either case likely versions of pcl need to be produced with newer dependencies. Thank you.

Yes, that is the reason why I opened conda-forge/conda-forge-pinning-feedstock#7412 . vtk 9.4.1 builds have several problems, so it is easier to just concentrate the work on vtk 9.4.2 .
