How to use the Components.Headers

Similar to https://github.com/danielgtaylor/huma/issues/495

I want to define a common header that is documented and reused by a group of API.

What's the correct way to ref the header in the group or each Operation Register?

I see there's Security field on the Operation to referecne the Components.SecuritySchemes

so what about for Headers?

Start with the Components.Headers, Components.SecuritySchemes, and Operation Register entry points named in the issue, then inspect the existing API documentation for how reusable components are referenced. Done means documenting the supported way to define and reuse a common header across a group of APIs or operations.
