Update external_airtable_transit_tech_stacks_services.yml

[fsalemi]

Description

The Services table in the Transit Technology Stacks base (Airtable) is a synced table from the Services table in the California Transit base. During the syncing process, all lookup fields are transformed into plain text fields. This leads to multiple type mismatch errors when creating the external table via the related DAG.
For example:

Error while reading table: cal-itp-data-infra.external_airtable.transit_technology_stacks__services, error message: JSON parsing error in row starting at position 51112: Could not convert value 'string_value: "279, 4"' to integer. Field: itp_id__from_provider_; Value: 279, 4 File: gs://calitp-airtable/transit_technology_stacks__services/dt=2022-08-16/ts=2022-08-16T14:33:57.365242Z/services.jsonl.gz

To address this, I'm explicitly adding the schema_fields and including only the required fields to prevent these parsing errors.

Terraform plan in iac/cal-itp-data-infra-staging/airflow/us

Plan: 1 to add, 0 to change, 1 to destroy.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
-/+ destroy and then create replacement

Terraform will perform the following actions:

  # google_storage_bucket_object.calitp-staging-composer["dags/create_external_tables/airtable/external_airtable_transit_tech_stacks_services.yml"] must be replaced
