Read vocabularies from the data/controlled-vocabularies directory
instead of exporting them from the schema itself. Also, I use the
name vocabulary.txt for all of them on the site since they are in
each field's directory already.
This script doesn't generate the docs itself. It actually only does
the schema parsing to generate the metadata term content and vocabs.
The docs site is generated by Hugo after running this.
This script parses the Excel schema file to produce term metadata
and extract controlled vocabularies to the site content directory.
After running this we can generate the site using Hugo.
