[gshank]

resolves #4940

Description

This creates new third-party-stubs/mashumaro and adjusted those files to pass mypy.

It has a bug in doing to_msgpack():

/Users/gerda/FTA/dbt/core/dbt/parser/manifest.py:549: in write_manifest_for_partial_parse
    manifest_msgpack = self.manifest.to_msgpack()
/Users/gerda/FTA/dbt/env/lib/python3.8/site-packages/mashumaro/mixins/msgpack.py:44: in to_msgpack
    self.to_dict(**dict(**to_dict_kwargs))
<string>:24: in to_dict
