fix: Third party identifiers parsing

Current version requires that third party ids contains the fields
`validated_at` and `added_at`, but Synapse admin API documentation does
not list those fields in `create_or_modify` endpoint: https://element-hq.github.io/synapse/latest/admin_api/user_admin_api.html#create-or-modify-account

Since those fields are currently required, the endpoint may fail to
deserialize legitimate requests.
