Redirect setup-rclone to AnchorFree pinned fork

Redirect AnimMouse/setup-rclone to our pinned fork

What

Rewrites all uses of AnimMouse/setup-rclone to our fork AnchorFree/setup-rclone, pinned to a full-length commit SHA:

AnimMouse/setup-rclone@… -> AnchorFree/setup-rclone@22265f6f0d55cda70cba829a3047a24d4e81f797 # v1.0.0

Why

The upstream AnimMouse/setup-rclone is an action that references other actions internally (transitive uses:). Those transitive references are not pinned to commit SHAs, and the upstream maintainer does not want to pin
them. That blocks us from enforcing full-length-SHA pinning across our actions, since the policy also applies to actions nested inside the composite actions we consume.

To resolve this, the fork AnchorFree/setup-rclone was created. The only difference in the fork is that its internal/transitive action references are pinned to commit SHAs. There are no behavioral changes — it does exactly what upstream does.

Impact

• No change in behavior; the fork is functionally identical to upstream.
• All setup-rclone references now resolve to an immutable commit SHA, end to
  end (including transitive actions), satisfying SHA-pinning.
