Standardized Documentation Format a la Swagger

[alexdavis24]

Is your feature request related to a problem? Please describe.
Coming from a a world of Swagger/OpenAPI, there is a clearly defined documentation template around exposing an API. We would like to expose Temporal Workflows as part of a larger service, where a Temporal Workflow plays the role of a "black box" service call, and accordingly the front-end dev should know only what input parameters/return values are expected for a particular workflow, with the rest of the workflow abstracted away.

Swagger/OpenAPI has a clearly defined structure to share between end users:
https://swagger.io/docs/specification/v3_0/basic-structure/

Describe the solution you'd like
Is there a possibility of Temporal

1. defining a consistent structure to use across projects and
2. Creating tooling that can read in the consistent structure to generate a human-friendly documentation page, etc.?

Describe alternatives you've considered
Custom yaml files that are shared across teams - this requires teams to agree on their own internal standards and makes reuse of documentation across projects difficult
