getHttpClient from service does not forward mia headers

[FabioNappi]

The docs do not discriminate between the getHttpClient functions decorated to the fastify instance and request instance, but there is a difference indeed.

Using the above function decorated to the fastify instance, the obtained client will not forward Mia headers; while using the same function decorated to the request instance, the obtained client will actually forward those headers.

I would expect that the client obtained from the fastify instance is still able to forward mia headers or at least point this difference in the docs.

environment

Is it not possible to access to the headers from the instance. So, we should add the limitation in docs I suppose. Can you open a PR?
