Error message for reaching maximum number of concurrent DNS queries is not explicit.

Issue description

After #59445 upped the maximum concurrent DNS queries at any given time, it is much less likely to reach the limit, but not impossible. And should it occur, the console outputs:

Condition ' resolving == IP::RESOLVER_INVALID_ID ' is true. returned: ERR_BUG

This error message can potentially be very confusing. misleading and, compared to most other error messages in Godot, it looks quite cryptic. If the users doesn't know where to look, it's bound to cause a few headaches
Ideally, it should tell the user exactly what happened (the query limit has been reached), and potentially instruct the user on how to fix it (tone down the requests, or increase the limit, the latter of which should probably not be encouraged)

Steps to reproduce

No need.

Minimal reproduction project

No response

#59445 added error messages, but the error is actually emitted elsewhere.

The limit is hardcoded, so you need to recompile the editor and export templates from source to change it.
