Fix helm_release values causing perpetual diffs due to line ending differences

[raman1236]

Description

Fixes #543

When values YAML files have CRLF line endings (common on Windows) but state was stored with LF line endings (from Linux/Mac), Terraform detects spurious diffs and plans unnecessary changes.

Solution

Added a list plan modifier (normalizeLineEndingsList) for the values attribute that normalizes CRLF (\r\n) line endings to LF (\n) before comparison. If the values are semantically identical (only differing in line endings), the plan is suppressed.

How It Works

// In the plan modifier:
normalizedPlan := strings.ReplaceAll(planStr.ValueString(), "\r\n", "\n")
normalizedState := strings.ReplaceAll(stateStr.ValueString(), "\r\n", "\n")
if normalizedPlan != normalizedState {
    equal = false
}

Testing

• Verified compilation succeeds
• When values only differ by line endings, no plan changes are detected
