Broken instrumentation for google.golang.org/grpc 1.61

[mariomac]

Concretely, the fields: localAddr and remoteAddr have been removed from google.golang.org/grpc/internal/transport/http2Server in some version of GRPC > 1.58.3 and <= 1.61.0.

This would make gRPC instrumentation stop working for services with updated libraries.

It seems already addressed but after updating, our integration tests failed. Let's see if we need to fix the tests or there is a bug.

Our integration tests seem to fail for GRPC >= 1.61:

        	Error Trace:	/Users/mmacias/code/beyla/test/integration/traces_test.go:205
        	            				/Users/mmacias/code/beyla/test/integration/traces_test.go:170

Fixed in #609
