feat: support other types of release metadata

[varlucian]

This should fix the test workflow:

      - uses: ./
        with:
          name: cli/cli
          tool: gh

where gh macOS binaries don't have darwin in the name, but gh_2.74.2_macOS_amd64.zip.

And the crane download:

        uses: isometry/setup-generic-tool@1a641516469c4d463e5ec9eaed53b54e5a7864fc # v1.2.0
        with:
          name: google/go-containerregistry
          version: v0.20.6
          tool: crane
          asset: go-containerregistry

by adding the last name, since the metadata doesn't contain the tool name (crane in this case), but another asset name go-containerregistry.

Also, enabled test to run on Pull Request and now they are successful
