Documentation Fix

[mrnolte]

This PR fixes #305. Multiple things had to be touched, as the switch from RDF/XML to functional syntax was not the only issue.

1. documentation.yaml, evaluation.yaml and SOMA-vocabulary.tex have been adapted so that the Evaluation workflow does not use the raw SOMA files, but the ones generated by the evaluation (these are uploaded as artifacts).
2. Two annotations in SOMA-AGENT were incorrectly labels instead of comments; the documentation did not like the contained line breaks.
3. owl-reader.py now correctly escapes latex special characters such as _.
4. SOMA-ACT had one class, NonmanifestedSituation, which used the incorrect separator / instead of # between namespace and fragment.

The Release Notes have been updated, including a sentence about USD.owl.
