DEV: Try another workaround for `getaddrinfo: Temporary failure in name resolution` (#27410)

This commit tries another work around for the `Socket::ResolutionError: getaddrinfo: Temporary failure in name resolution`
error we are seeing on CI.

The problem with the previous workaround is that `Capybara.using_session` will attempt to resolve `localhost`
before yielding the block which means our retry code is not hit.

This problem may be related to https://bugs.ruby-lang.org/issues/20172
which hints at us potentially not being able to spin up threads on CI so
I'm adding a debugging statement when stuff fails.
