fix(profiles): follow the CentOS Stream cloud image rename

[alban]

AIL:4

CentOS Stream switched its composes to the "gen2" pungi configuration on 2026-08-19 (c9s, c10s), which dropped the CentOS-Stream-GenericCloud-x86_64 image name. cloud.centos.org now serves CentOS-Stream-GenericCloud-<N>-latest.x86_64.qcow2, and the old CentOS-Stream-GenericCloud-x86_64-<N>-latest.x86_64.qcow2 URLs return HTTP 502.

Since then every CentOS Stream target fails with infra_error (download image: unexpected HTTP status 502 ...). For example, all centos-stream-9-5.14 cells in Inspektor Gadget's weekly compatibility run have been infrastructure errors since 2026-09-28: https://github.com/inspektor-gadget/inspektor-gadget/actions/runs/37271031045

This updates the URL in the CentOS Stream 9/10 profiles (including the generated kernel-sweep ones) and in make vm-images-extended.

Walkthrough

CentOS Stream 9 and 10 image URLs now use the updated GenericCloud filenames. The change updates the extended image fetch target and affected VM profiles; cache destination names remain unchanged. The changelog records HTTP 502 errors from the previous URLs.

Changes

CentOS Stream image URLs

Layer / File(s)	Summary
Update image URLs in fetch target and profiles vm/profiles/centos-stream-*.yaml, Makefile, CHANGELOG.md	The fetch target and affected VM profiles use filenames with the stream version before the architecture suffix. The fetch target keeps its existing cache destination names. The changelog records HTTP 502 errors from the previous URLs.

Full details: Missing Regression Tests

Explanation

The PR changes observable image-download behavior but adds no regression test. The diff changes the CentOS Stream 9/10 URLs in Makefile:219-240 and in five profile YAML files. These URLs drive downloads through scripts/fetch-matrix-images.sh and vm/scripts/fetch-cloud-image.sh. Existing internal/vm/profile_catalog_test.go:8-31 checks only that profiles parse and have unique IDs, and scripts/fetch-matrix-images_test.sh:20-55 uses unrelated example URLs. No test file changes exist in the PR, and no test asserts the new CentOS filenames.

Resolution

Add an automated regression test that loads the CentOS Stream 9/10 profiles and asserts the exact source_url values, including the generated kernel-sweep profiles. Also inspect the vm-images-extended Makefile recipe and assert that it uses CentOS-Stream-GenericCloud-9-latest.x86_64.qcow2 and CentOS-Stream-GenericCloud-10-latest.x86_64.qcow2 while preserving the existing cache paths. Keep the assertion independent of live network availability.
