Fix conda release with rattler

Fix the rattler-build line in the conda release action. 

This fails: `rattler-build upload anaconda -o netzoo rattler-build/**/*.conda`

But the manual version of the conda release should work: 

`rattler-build upload anaconda -o netzoo --api-key ${{ secrets.ANACONDA_TOKEN }} output/**/*.conda`

Check what changes have been made in the manual one.
