Add tardigrade genomes to the CVMFS resource

Per [this Galaxy Help ticket](https://help.galaxyproject.org/t/adding-the-tardigrade-h-exemplaris-genome-to-galaxy/12160/2), please add two tardigrade genomes (_H. exemplaris_ and _R. varieornatus_) to the CVMFS resource.

Please see below for the information that you'll need. It wasn't entirely clear to me what the dbkey and id fields should be, so I used the Assembly name for both.

**_H. exemplaris_**:
dbkey: nHd_3.1
description: "Hypsibius exemplaris Z151"
id: nHd_3.1
fasta URL: https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_002082055.1/
reference annotation link: https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_002082055.1/

**_R. varieornatus_**:
dbkey: Rvar_4.0
description: "Ramazzottius varieornatus YOKOZUNA-1"
id: Rvar_4.0
fasta URL: https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_001949185.1/
reference annotation link: https://www.ncbi.nlm.nih.gov/datasets/genome/GCA_001949185.1/

Locate the CVMFS resource configuration and compare how existing genome entries are represented. Add entries for H. exemplaris and R. varieornatus using the supplied dbkeys, descriptions, IDs, FASTA URLs, and annotation links; done means both genomes are included in the resource with their requested metadata.
