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

Browse Source 
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.

# This is a monkey patch for the `Capybara.using_session` method in `capybara`. For some
# unknown reasons on Github Actions, we are seeing system tests failing intermittently with the error
# `Socket::ResolutionError: getaddrinfo: Temporary failure in name resolution` when the app tries to resolve
# `localhost` from within a `Capybara#using_session` block. Therefore, we will ensure we can resolve `localhost` first
# before starting the new session.
