Future-proof flask_limiter.Limiter.__init__

We currently use Flask-Limiter 2.7.0. Upgrading to 3.1.0 breaks

https://flask-limiter.readthedocs.io/en/stable/changelog.html#v3-0-0

Not updating the lockfile here, pending @ZorbaTHut testing some infra
updates; however, this is necessary to be able to do so, and it still
works in 2.7.0.
