fix: correct authorization header spelling in api docs (#27721)

Corrects the misspelled `Authorizaiton` Swagger header name to
`Authorization` in the source annotation and checked-in generated API
documentation.

This prevents generated API specs and SCIM examples from documenting the
wrong HTTP header name.
