v5.2.4: Reuse cached signed checksums when restoring mise

Jobs that restore mise from the cache no longer have to download its signed checksums from GitHub on every run, so a network failure at that step no longer fails a job that otherwise restored correctly.

Fixed

• Restoring a cached mise no longer needs a network download of the checksums. The action checks the cached mise binary against the signed SHASUMS256.txt and its .minisig. Before this release it downloaded both files from GitHub on every run, even when the cache restored correctly. When that download failed, for example after repeated curl errors, the job failed. Now, once the signature checks out, the action saves both files as SHASUMS256-<version>.txt and .minisig in <mise_dir>/bin, which is part of the mise cache. On later runs it reads them from the restored cache and checks the minisign signature again before using them. If the files are missing, corrupt or tampered with, the action downloads them as it did before. There are no new inputs. (#708 by @jdx)
  • Caches saved by earlier versions don't contain these files. The main cache is only saved on a cache miss, so runs keep downloading the checksums until the cache is saved again or its key changes.
