feat: add --write-output flag to helmfile fetch for air-gapped environments (#2572)
* feat: add --write-output flag to helmfile fetch for air-gapped environments

Add --write-output flag to helmfile fetch that outputs a modified
helmfile.yaml with chart references updated to point to downloaded
local chart paths. Combined with --output-dir, this enables preparing
all charts for deployment in air-gapped environments.

Usage:
  helmfile fetch --output-dir ./charts --write-output > helmfile-airgapped.yaml

Fixes #2571
