Passport is used by Google Auth in API, to test: confirm you can login & logout of this pizza

Removed vultr server and associated DNS entries

We previously had issues upgrading this dependency. Once it hit staging and we hit /logout the following error was logged - https://opensystemslab.slack.com/archives/C4B0CKQ3U/p1658848785967489

I then downgraded here - #1037

There is an override in package.json which should keep up clear of the affected sub-dependency, but upgrading passport would be good to do. Looking at the issues there and at session-cookie I'm not sure the issue is currently fixed.

I can logout of the pizza just fine, but a console error is thrown. Happy to try again for sure on this one 👍

Upgrade the passport dependency

[builditben]

I can logout of the pizza just fine, but a console error is thrown.

I tried to replicate this issue and I did get a console error on login (Ee is not a function: https://john-opensystemslab-io.airbrake.io/projects/329753/groups/3392339330205850107?tab=overview). This error doesn't seem to be related to this specific upgrade though. I was able to replicate the same bug on a different pizza without this change.

I could not replicate the previous error related to this upgrade (the one @DafyddLlyr mentioned: TypeError: req.session.regenerate is not a function).

I've tested this change as thoroughly as I can and can't see where the previous issues were coming from. I'd suggest promoting to staging for more testing.

[DafyddLlyr]

Thanks @builditben for the thorough testing here - if you could please merge this to main just now it will trigger a deploy to staging where we can test.

If all's good there let's push try and push this single change onwards to production also today and draw a line under it 💪
