doc: add note about resource type in async_hooks
Hi everyone
During the last Diagnostic WG meeting, the question has been raised of the type
argument interface (async_hooks
/ init
hook).
The initial demand was to document more precisely each type. But @bmeck mentions that this list of identifiers described in the documentation could arbitrarily change.
So, this pull request contains a note to explicitly tell users what is the status of these identifiers.
