"Exporting data" tutorial describes input artifacts as output artifacts

[AmandaBirmingham]

Bug Description
The "Exporting Data" tutorial correctly provides the input artifacts needed to run the example export commands, but labels them as "Output artifacts". This is the case for both examples given in the tutorial. The tutorial does not provide output file(s)/folders (which of course would not be artifacts for these commands).

Expected behavior
Input artifacts are labeled as such rather than as "Output artifacts". In a perfect world, output file(s)/folders are provided so users can see what the export commands actually produce.

Screenshots
Example of unexpected labeling:

Comments
I suspect this is in some way due to the automated document processing used to generate the tutorial pages, so perhaps it cannot actually be fixed, but I thought it was worth noting.

Thanks for noticing and sharing that @AmandaBirmingham! This is an issue with our docs build. As we're transitioning how we manage the user docs, and phasing this site out in favor of https://use.qiime2.org, we're not going to fix for this release but rather just make sure that we don't introduce the same issue in the new docs.

Closing in favor of caporaso-lab/using-qiime2#16.
