build(deps): bump actions/download-artifact from 7 to 8

[dependabot]

Bumps actions/download-artifact from 7 to 8.

Release notes

Sourced from actions/download-artifact's releases.

v8.0.0

v8 - What's new

[!IMPORTANT] actions/download-artifact@v8 has been migrated to an ESM module. This should be transparent to the caller but forks might need to make significant changes.

[!IMPORTANT] Hash mismatches will now error by default. Users can override this behavior with a setting change (see below).

Direct downloads

To support direct uploads in actions/upload-artifact, the action will no longer attempt to unzip all downloaded files. Instead, the action checks the Content-Type header ahead of unzipping and skips non-zipped files. Callers wishing to download a zipped file as-is can also set the new skip-decompress parameter to true.

Enforced checks (breaking)

A previous release introduced digest checks on the download. If a download hash didn't match the expected hash from the server, the action would log a warning. Callers can now configure the behavior on mismatch with the digest-mismatch parameter. To be secure by default, we are now defaulting the behavior to error which will fail the workflow run.

ESM

To support new versions of the @actions/* packages, we've upgraded the package to ESM.

What's Changed

• Don't attempt to un-zip non-zipped downloads by @​danwkennedy in actions/download-artifact#460
• Add a setting to specify what to do on hash mismatch and default it to error by @​danwkennedy in actions/download-artifact#461

Dagger benchmarks: dirty vs master

Counts are benchmark metrics (time, allocations, bytes). Timing changes require non-overlapping median ± IQR bands; both revisions need at least five timed samples, and timing regressions need an independent confirmation run.
