removed chart is still referenced

[sgandon]

We have changed the URL for our charts to only publish "stable" charts in the hub.
see #213 .
And therefore some charts where removed and not accessible anymore through the old url.
But they are still referenced in the hub :
https://hub.helm.sh/charts/talend/talend-api-microgateway
https://hub.helm.sh/charts/talend/tpsvc-remote-engine
The 2 above charts are not available any more, and more over their url is not a chart index anymore.
How can I make sure those 2 charts are dereferenced ?

Sorry about that, I forgot to update the config/repo-values.yaml, just ignore this issue.
