feat: Build Airbyte Protocol js-schema files for use in schemastore

[evantahler]

This pr adds the creation of both 'latest' and versioned JS versions of the Airbyte Protocol for use with https://www.schemastore.org.

1. New utilities that produce JS versions of the protocol at the below paths. We want to keep these files in the main branch of this repository for easy access. The docker command wraps the node command to run on GHA. Run ./protocol-models/bin/generate-schemastore-docker.sh locally to try it
   • /airbyte-protocol/jsonschema/latest/airbyte_protocol.json
   • /airbyte-protocol/jsonschema/{version}/airbyte_protocol.json
2. pull-request-publish will run this new command when the bot creates a new PR (e.g.) for a version bump. This lets the PR reviewer see the changes, and we won't be writing directly to the main branch of the repo.

These changes in aggregate allow for a simple default schematore entry (e.g.) with the following content, once we merge this:

    {
      "name": "Airbyte Protocol definition",
      "description": "JSON schema for Airbyte Protocol",
      "fileMatch": [
        "airbyte_protocol.yml", 
        "airbyte_protocol.yaml"
      ],
      "url": "https://github.com/airbytehq/airbyte-protocol/raw/main/airbyte-protocol/jsonschema/latest/airbyte_protocol.json"
    }

AJ - I totally forgot about this. Are you still interested in have SchemaStore entries for the Airbyte Protocol? I think this mostly works...
