In #1001 bits around the Helm repository reconciliation logic were rewritten, mostly based on the documented behavior instead of the actual code. This resulted in the reintroduction of a YAML marshal of the (sorted) index YAML instead of reliance of just the checksum of the file. This to take situations into account in which a repository would e.g. provide a new random order on every generation. However, this approach is (extremely) expensive as the marshal goes through a JSON -> YAML loop, eating lots of RAM in the process. As the further (silently) introduced behavior has not resulted in any reported issues, I deem this approach safe and better than e.g. encoding to just JSON which would still require a substantial amount of memory.

ghcr.io/fluxcd/source-controller:rc-e5c0313dIn #1001 bits around the Helm repository reconciliation logic were rewritten, mostly based
on the documented behavior instead of the actual code. This resulted in the reintroduction
of a YAML marshal of the (sorted) index YAML instead of reliance of just the checksum of
the file.
This to take situations into account in which a repository would e.g. provide a new
random order on every generation. However, this approach is (extremely) expensive as
the encoder goes through a JSON -> YAML loop, eating lots of RAM in the process.
As the further (silently) introduced behavior has not resulted in any reported issues, I deem
this approach safe and better than e.g. encoding to just JSON which would still require a
substantial amount of memory.
Fixes fluxcd/flux2#3620
