Pin both seurat and seuratobject versions

[SGMartin]

Some people are having issues due to them installing the correct Seurat version (v4) but pulling (I guess from conda) SeuratObject v5. This works with seurat due to compat. options but makes beyondcell fail when calculating the bcScore.

This should be fixed by either:

• Pinning both Seurat and SeuratObject versions in the beyondcell recipe.
• Upgrading Beyondcell to fully support v5 objects.

So after digging in the conda recipe I've found that the issue lies specifically with the noarch compilation, which is mostly pulled by Windows based installation. AFAIK, linux and macOS are compiled as standalone versions, so that's why we could not reproduce it on our end.
