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
