Support cases with no arch or platform in the artifact name

[t3mi]

Please add support for cases when binary was published using custom naming scheme like without platform/architecture. Currently, the action is failing as it can't find the binary:

- uses: jaxxstorm/[email protected]
  with:
    extension-matching: disable
    rename-to: cli
    repo: <private repo>/cli
    tag: latest
    token: ***
