feat!: use cat-vrs-python + va-spec-python

[korikuzma]

close #388 , #395, #309

• Breaking changes
  • Update/add ga4gh packages
    • Add ga4gh.cat_vrs + ga4gh.va_spec packages
      • The Pydantic models in these packages replace the manually created models in metakb/schemas/annotation.py, metakb/schemas/categorical_variation.py, and metakb/schemas/variation_statement.py. (use cat-vrs-python and va-spec-python #388)
    • ga4gh.vrs version bumped
    • The models in all ga4gh packages caused breaking changes (mainly renaming) to the evidence models (such as Revise "Study" node type to "Statement" #395)
    • Represent categorical variation members and constraints properly (Move variant.definingContext.expressions to variant.members #309)
  • Standardize representing normalizer data in extensions
    • The extension.name will always be vicc_normalizer_data and value will contain id, label, and optional mondo_id (for disease)
• Simplify assertion checks in tests

Note: I started doing study --> study statement / statement, but with an already large PR I decided to break this out. Will create new PR with this change.

Going to take another look at this in the morning to see if I missed anything. Afterwards, I'll request your review @mcannon068nw

looks good to me, no major concerns
