Document Alliance Genotype modular ingest

[kevinschaper]

Add a modular ingest using our ingest cruft template that brings in genotypes and associations to genotype components

Already started at: https://github.com/monarch-initiative/alliance-genotype-ingest

Rough outline of steps

• [x] download yaml
• [x] transform python
• [x] transform yaml
• [x] tests
• [x] documentation
• [x] import into monarch-ingest

Somewhat blocked by needing appropriate predicates for genotype to allele associations, but additional testing and doc can go in. We could also scale this back somewhat and just bring in the genotypes initially for use with GenotypeToPhenotype associations
