Fix interactive apply asks in no change situation (#945)

This commit makes the apply logic exit early in the event there are no
changes to releases. I believe this effectively reverts helmfile#522.

Updates relevant snapshots

Clarify conditions under which preapply hooks are triggered to include that they will no longer fire if there is a no-op.
Docs as requested by the maintainer from a copilot request made by them.

Fixes: helmfile#679
