Fixes #30891
* Upgrade `graphite-web`, `carbon` and `whisper` from 1.0.2 -> 1.1.3.
* Replaced the deprecated `pythonPackages.graphite_influxdb` with
`pythonPackages.influxgraph.`
* Renamed `pythonPackages.graphite_web` to `pythonPackages.graphite-web`
to be consistent with the Python package name.
* Replaced the unmaintained `pythonPackages.graphite_pager` with
`pythonPackages.graphitepager`
* Moved all new packages from `python-packages.nix` to
`pkgs/development/python-modules`
