feat: reuse the goreleaser binary from the runner tool cache (#577)

* feat: cache the goreleaser binary

Look for GoReleaser in the runner tool cache before a download. This
makes a second use of the action in the same job, or any job on a
self-hosted runner, install immediately.

Add an opt-in `cache-binary` input that also stores the binary in the
GitHub Actions cache. When it hits, the action does not download the
release archive, the checksums and the signature bundle again. Cache
errors are not fatal and fall back to a download.

The runner tool cache entry is now keyed by distribution, so a Pro
binary is no longer returned for an OSS install of the same version.

Closes #476

* refactor: collapse the duplicated zip extract branches

Both branches called extractZip with the same destination after the
install rewrite, so only the source path differs now.

* fix: drop the GitHub Actions cache layer, keep the tool cache lookup

Review found that the GitHub Actions cache layer cost more than it
saved. Measured on ubuntu-latest, same job, same version:

  cold: download + checksum + cosign + extract   0.93 s
  cache hit: restore the 24 MB entry             1.28 s
  first run also pays a save                    +2.26 s

It is slower than a download in every configuration measured, because a
GitHub-hosted runner reaches the release CDN in about 0.4 s for a 15 MB
archive, and the cached entry is the larger extracted directory.

It also skipped the sha256 and cosign verification on a hit, which is
the control it was supposed to protect, and the only case where it wins
on time is when cosign is installed, which is exactly the case where
skipping is wrong. It cost 875 KB (+120%) of dist/index.js for every
user and 24 MB of repository cache quota per version and platform.

The restore and save wrappers were also dead code: @actions/cache
catches everything except ValidationError internally, so the try/catch
and the ReserveCacheError classification could never run.

What remains is the runner tool cache lookup, which is what #476 asked
for, and the distribution-keyed tool name that stops a Pro binary being
returned for an OSS install.

The tool cache test asserted that two installs return the same path, but
that path is a pure function of the tool, version and architecture: it
passed even with the tool cache wiped between the calls. It now asserts
that the second install reports a tool cache hit and does not download,
and it was verified to fail when the lookup is removed.

* docs: drop the GitHub Actions cache rationale from the README

Review feedback: the paragraph explaining why the action does not use the
GitHub Actions cache is not needed. The measurements stay in the pull
request for anyone who asks again.

Also rebuilds dist for js-yaml 5.4.1, merged from master in #578.

* fix(cache): preserve verification guarantees

Keep checksum-skipped downloads out of the persistent tool cache and separate checksum-only entries from cosign-verified entries.

+### Cache the binary
+
+The action looks for GoReleaser in the [runner tool cache][toolcache] before it
+downloads. A second use of the action in the same job, or any job on a
+self-hosted runner that already has the version, installs immediately.
+
+A binary taken from the tool cache is not verified again. The cache records
+whether checksum or checksum and cosign verification completed. When cosign is
+available, the action only reuses a signature-verified entry. A binary whose
+checksum could not be verified is used for that invocation but is not cached.
+
+On a self-hosted runner the tool cache is kept between jobs, so it must be
+trusted like the runner itself. GitHub-hosted runners start with an empty tool
+cache in every job, so they always download and verify.
