Kacper Sawicki 134924ded0 ci: add fallback for helm install when get.helm.sh is down (#21268)
Add a fallback step that installs helm via apt from Buildkite's
repository if the primary `azure/setup-helm` action fails. This makes CI
resilient to `get.helm.sh` outages while preserving the caching benefits
of the action when it works.

## Changes

- Primary: `azure/setup-helm` with `continue-on-error: true`
- Fallback: apt install from Buildkite's helm-debian repository (only
runs if primary fails)

The fallback uses GPG-signed packages from the [official Helm apt
repository](https://helm.sh/docs/intro/install/#from-apt-debianubuntu)
hosted by Buildkite.

## Background

On Oct 29, 2025, `get.helm.sh` experienced an outage that broke CI. A
workaround was applied (#20552) but later reverted. This PR makes the
workaround automatic - it only kicks in when needed.
