[OpenAPI-1.1] Add the current generated OpenAPI spec file to each API repo

Ensure each of the following repos has a copy of latest openapi spec file committed. For consistency, these should all have same name (i.e. openapi.yaml) and be in the root of the repo.

• Card
• Photo
• Staff
• Student
• Institution Identifiers
• Lookup

Note:

• Institution Identifiers repo may not have a way to generate a spec
• Lookup, already has an openapi.yaml though generation appears to only include 'GET' endpoints!
• For repos where running the API locally auto-generates the OpenAPI spec, alter the flow to store the generated spec in the repository (for convenience).
