fix(test): update ip of example.com

[situ2001]

When running test of my app, I found that the test failed due to the IP of example.com being changed and also discovered that hickory dns has the same issue. So I proceeded to take the following steps to fix the test.

1. Change IPv4: from 93.184.216.34 to 93.184.215.14
2. Change IPv6: from 2606:2800:220:1:248:1893:25c8:1946 to 2606:2800:21f:cb07:6820:80da:af6b:8b2c

I searched for all occurrences and replaced them until cargo test is passed. And I'm unsure whether I need to do anything more for the tests that run locally. For example,

hickory-dns/tests/integration-tests/tests/sqlite_authority_tests.rs

Line 55 in 76a4b84

assert_eq!(record.data().unwrap(), &RData::A(A::new(93, 184, 216, 34)));

Reference: Here is another repo that fixed this issues 1d ago Chia-Network/chia-blockchain#17894

I hope you can review it patiently, as there are many files involved in the changes. Thank you. Additionally, do we need to add a global variable or environment variable to handle future IP changes?
