boat-angular only deprecates one of the overloaded function signatures for deprecated operations

[daiscog]

Current behaviour

The typescript client generated by boat-angular have several overloaded function signatures per operation depending on what the caller wants to observe as the result (i.e., return just the response body, the whole HttpResponse entity, or a stream of HTTP events).

When an operation is deprecated, only the first of these overloads are marked as deprecated:

This means the IDE/linter of anyone using any of the other function signatures does not warn them that the endpoint is deprecated:

(note only two of the calls are marked deprecated above)

Expected behaviour

All overloaded function signatures for a deprecated operation are marked as deprecated.
