Add version IRI to taxslim

[dosumis]

Just came here to request this. Needed for CAP pipeline. @matentzn please can you give @ubyndr permissions and assign?

This needs this intervention:

• [x] Adding a ROBOT annotate command that injects IRI and version-IRI in the usual ODK way here: https://github.com/obophenotype/ncbitaxon/blob/master/subsets/Makefile#L7

Note that it seems like the main ncbitaxon does not have this: https://github.com/obophenotype/ncbitaxon/blob/master/Makefile#L25

But it is embedded here: https://github.com/obophenotype/ncbitaxon/blob/master/src/ncbitaxon.py#L202
