Kranthi Poturaju 085b8e14fb docs(action): add missing input defaults and fix cache-hit description
- Add  to  and  inputs, making the absence-of-value behaviour explicit and consistent with all other optional inputs in the file.
 - Expand the  output description to document all three observable states: 'true' on exact key match, 'false' on partial restore-key match or unavailable cache service, and not set when no cache entry is found (intentional; see actions/cache#1466).

deprecationMessage: |
save-always does not work as intended and will be removed in a future release.
A separate `actions/cache/restore` step should be used instead.
See https://github.com/actions/cache/tree/main/save#always-save-cache for more details.
outputs:
cache-hit:
description: "A boolean value to indicate an exact match was found for the primary key. Returns 'true' on exact key match, 'false' on partial match via restore-keys or when the cache service is unavailable. Not set when no cache entry is found."
