Include version number in NameRes and maybe some kind of notification on updates

If we could incorporate the Babel version number (e.g. 2022oct13) into the NodeNorm Swagger version number (currently 2.0.9 from the Babel image), then a user could know what version was being used, and could refer to it in issues or look it up in downloads.

We store this information in the https://github.com/helxplatform/translator-devops/blob/e158e6264b894d85a761ce10ebfdb8f7c387ff25/helm/name-lookup/values.yaml file, so the easiest way to do this would be to store the Babel in an environmental variable, and then load it into the Python program. However, the obvious place to put this information is in api/resources/openapi.yml, which we use verbatim. So either:

• We need to modify this file on the fly while creating the instance, or
• We need to have the Python script modify the version while loading it, or
• We need another endpoint to provide this information, which can load that from the environmental variable we end up using.
