feat: allow downloading unzipped binaries

[sgoudham]

Hi 👋,

I'm quite interested in using this action, or more so the @extractions/setup-crate NPM library, to create an action which is able to download binaries which are not gzipped in the release assets. (i.e. catppuccin/whiskers)

From looking through the source code, I see that there's a strong assumption that it's always an extract-able directory. In the interest of time, I quickly mocked up an implementation where it's now assumed that if the download doesn't end with .zip, .tgz or .tar.gz then it is a "naked binary". Then, a temporary directory is created and the downloaded binary is moved into it, allowing the rest of the logic to succeed as normal. I have tested that this implementation works with the existing test suite as demonstrated in my fork's action run.

My preferred approach here would be to split out the logic into 2 separate paths (zipped or unzipped) based on the ending of the file, but that would require a much larger refactor and I was already unsure if this type of change would be accepted. I'd appreciate if you could let me know if you're interested in accepting this type of change before I spend more time on it. I'm more than happy to discuss implementation details going forward (the current code needs a bit of tidy up anyways)

Regardless of whether this PR proceeds, thanks for creating this action and the work you've put into it!
