ansible: replace old ubuntu1404 DO host with fedora38

Draft because the Jenkins service doesn't work:

May 10 09:46:56 test-digitalocean-fedora38-x64-1 java[931]: SEVERE: https://ci.nodejs.org/ provided port:41913 is not reachable on host ci.nodejs.org
May 10 09:46:56 test-digitalocean-fedora38-x64-1 java[931]: java.io.IOException: https://ci.nodejs.org/ provided port:41913 is not reachable on host ci.nodejs.org

@targos Since this is a new IP address you'll need to add it to the firewall for ci.nodejs.org (and possibly remove the old IP address if it's not being reused by us). FWIW instead of saving the current rules as foo before editing in practice we've been using filenames based on date/person doing the editing and haven't been removing them. I don't think there's a real reason/need for doing that (although I guess it does mean we could roll back to earlier iptables configs).

There is also a jenkins/host/iptables.yml playbook which in theory will configure iptables for ci.nodejs.org or ci-release.nodejs.org -- I'm not sure if it currently works for ci.nodejs.org (at one point I did fix it to work on ci-release.nodejs.org).

Thanks, I updated the firewall rules and Jenkins is now connected.
Test run: https://ci.nodejs.org/job/node-test-commit-linux/nodes=fedora-latest-x64/52059/

Build went fine, but there's a failing test. I tried to run it 10 times and it always fails:

    throw err;

I don't really know what to do about it...

[targos]

I suggest we merge this, because the machine replacement happened, and track the test failure in #3350
