Dear maintainer:

Please disable network tests in bookworm as well, as they have started to fail
even when network access is allowed during build:

[ RUN      ] net_test.address_creation
../tests/net_test.cc:110: Failure
Expected equality of these values:
   address15.host()
     Which is: "93.184.215.14"
   "93.184.216.34"
[  FAILED  ] net_test.address_creation (1 ms)

The test apparently expects www.example.com to have 93.184.216.34
as its IP address, but now it's 93.184.215.14.

Thanks.
