The current release workflows force a regeneration of the Helm index after the old (unmaintained) releases are removed from the Apache dist release SVN server. This causes previous releases to be removed from the Helm index (apache#3500). This commit is a tentative fix that re-generates a Helm index across `downloads.apache.org` as well as `archive.apache.org`. The logic is as follows: 1. All Helm charts from `downloads.a.o` and `archive.a.o` are downloaded locally so that the index is fully rebuilt across all versions. 2. The URL of any Helm chart that is located on `archive.apache.org` but not on `downloads.apache.org` is replaced by an absolute URL to `archive.apache.org`. That way, previous releases are always accessible. 3. The URL of any Helm chart that is located on `downloads.apache.org` is replaced by a relative path `${version}/polaris-${version}.tgz`. That way, the Helm index can be rebuild before a release vote is started, as the relative path will work regardless of the location being used (dist dev during RC vote, dist release and `downloads.a.o` after vote).

The current release workflows force a regeneration of the Helm index after the old (unmaintained) releases are removed from the Apache dist release SVN server. This causes previous releases to be removed from the Helm index (#3500).
This commit is a tentative fix that re-generates a Helm index across
downloads.apache.orgas well asarchive.apache.org. The logic is as follows:downloads.a.oandarchive.a.oare downloaded locally so that the index is fully rebuilt across all versions.archive.apache.orgbut not ondownloads.apache.orgis replaced by an absolute URL toarchive.apache.org. That way, previous releases are always accessible.downloads.apache.orgis replaced by a relative path${version}/polaris-${version}.tgz.That way, the Helm index can be rebuild before a release vote is started, as the relative path will work regardless of the location being used (dist dev during RC vote, dist release and
downloads.a.oafter vote).This PR is a draft to show how a solution could be implemented and to offer a path forward to work around #3500 until a permanent fix is added to the release workflows. Most likely the current code will be split and integrated into the pre-vote release workflow.
