CI failures on "Wait for Flux to be ready..."
Since recently (yesterday night ? this morning ?) we see quite a few early failure on `main`:
```
⏳ Wait for Flux to be ready...
...
```
(time-out)
In flux controllers logs, we see stuff like:
```
{"level":"error","ts":"2026-05-22T07:28:17.090Z","logger":"setup","msg":"unable to load feature gates","error":"feature-gate 'CancelHealthCheckOnNewRevision' not supported"}
```
```
{"level":"error","ts":"2026-05-22T07:28:05.073Z","logger":"setup","msg":"unable to load feature gates","error":"feature-gate 'UseHelm3Defaults' not supported"}
```
(from https://gitlab.com/sylva-projects/sylva-core/-/jobs/14498221499)
**See details below, the problem is that because of gitlab CI file caching and because of changes brought in https://gitlab.com/sylva-projects/sylva-elements/container-images/sylva-toolbox/-/merge_requests/645 and https://gitlab.com/sylva-projects/sylva-core/-/merge_requests/7773, our code wrongly concludes that the right version of sylva-toolbox is currently installed.**
