Adds an input that borrows the `save-always` input from [v4 of `actions/cache`][0], which will run the post step to save the cache even if a failure occurs. Using the added `cache-save-always` input saves the cache when a build fails, which will speed up subsequent runs which restore the partial build. This comes at the cost of requiring a build when there is an exact `key` match, since the cache from a failed build will have the same `key` as a completed build.

This will require a major version since this changes the noop-behavior on a full cache hit. If the trade-offs seem worthwhile (and I'm not missing anything about how Stack might treat these artifacts) then I'll bump the version and update the docs. |

Sounds good; I wasn't sure how to characterize the risk of removing the noop. The behavior is certainly the same and what is changed in the default scenario, not making use of the input, is an implementation detail. |

Saves the set of build artifacts after a build failure with a `-partial` suffix on the cache key. A full cache-hit will therefore only occur when restoring the cache saved after a successful build, allowing for the subsequent `stack build` and cache-save steps to be skipped.

Status check functions can only be used in `if` conditionals, so the use of a cache key suffix needs to be determined in a conditionally-run step.
This reverts commit dd40c85.
This reverts commit 629a6a9.
Checks that the workflow has not been cancelled (i.e., is succeeding or failed) and that `cache-save-always: true` when building and saving the cache. This extends the existing conditional on the `cache-hit` outputs, making the previously-implied `success()` check explicit. When `cache-save-always: false`, the default behavior is unchanged for the action: steps either no-op if a cache-hit occurred, or build and save otherwise. When `cache-save-always: true`, a building and saving the cache occurs on success or failure.
