Grafana 11.2 doesn't work with Go 1.23, so revert to 1.22. This can be
undone once we upgrade to a version containing
https://github.com/grafana/grafana/pull/92055, presumably grafana 11.3.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

ChangeLog: https://github.com/grafana/grafana/releases/tag/v11.1.0
A few additional changes were necessary:
* Grafana now refuses to listen on non-IP values and aborts with
Error: ✗ *apiserver.service run error: invalid IP address: localhost
* packages/grafana-e2e doesn't exist anymore, so the build fixes for
that could be removed.
* Make sure we always compile the binary parts of cypress.
* Grafana tends to set the minimum Go version to the latest Go version
available now[1].
* The `url` of a datasource was set to `localhost` by default. I don't
expect anybody to have not set it when needed, also Grafana aborts now
if `url` is non-empty for a random walk datasource (which broke the VM
tests).

Starting with v1.6.2, the plugin `grafana-oncall-app` changed the versioning schema in the upstream grafana plugin repository, adding a prefix "v" to every version. This creates a minor stylistic break in the current `grafanaPlugins` module, since it expects a version with just numbers and decimal points. By adding the versionPrefix arg, we preserve compatibility with other modules, while keeping with nixpkgs conventions.
