v1.5 release docs missing controlled vocabulary enum values

[bcorrie]

In the 1.5 docs (e.g. for pcr_target_locus) the enum values for controlled vocabularies are missing:

https://docs.airr-community.org/en/stable/miairr/data_elements.html

versus the 1.4 docs:

https://docs.airr-community.org/en/v1.4.1/miairr/data_elements.html

Something odd with the doc generation?
