This PR corrects a link found in two of the bwa modules meta.yml file. They did incorrectly point to a samtools website.

  • [x] PROFILE=docker pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • [x] PROFILE=singularity pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware
  • [x] PROFILE=conda pytest --tag <MODULE> --symlink --keep-workflow-wd --git-aware

I'm not sure how to proceed with these tests which are failing. Any input @mashehu ?

the conda ones are probably okay to ignore, the sha sum is often not reproducible with conda. Can you try to update the ones for sapme? I know you didn't touch the code itself, but it's always good if we try to fix the tests when they somehow start failing
