fix: reformat action pins JSON to 2-space indentation

[Copilot]

The three action pins JSON files were serialized with 4-space indentation, inconsistent with the 2-space standard used elsewhere and what marshalSorted in action_cache.go now produces.

Changes

• Reformatted .github/aw/actions-lock.json, pkg/actionpins/data/action_pins.json, and pkg/workflow/data/action_pins.json from 4-space to 2-space indentation

The files were stale from an older serialization path. The current marshalSorted already emits correct 2-space output; the data files just hadn't been regenerated to match.

-    "entries": {
-        "actions/cache@v4.2.3": {
-            "repo": "actions/cache",
+  "entries": {
+    "actions/cache@v4.2.3": {
+      "repo": "actions/cache",
