Allow to use the 'latest' release (with a named asset)

[carstingaxion]

Hello @stoph ,

thank you for providing this great service!

Today I wanted to use it within a blueprint.json to reference the latest release, without any need to change numbers regularly. But unfortunately only numbered releases seem to work. Like this example, where 0.28.0 is indeed the latest.

⛔ https://github-proxy.com/proxy/?repo=GatherPress/gatherpress&release=latest&asset=gatherpress.zip
✅ https://github-proxy.com/proxy/?repo=GatherPress/gatherpress&release=0.28.0&asset=gatherpress.zip

I described it like this in the PR with our use-case:

Internally github-proxy.com uses:

$url = "https://github.com/$repo/releases/download/$release/$asset";

which works fine with numbered, but not the latest release.

Acording to download - Is there a link to GitHub for downloading a file in the latest release of a repository? - Stack Overflow the url template needs some change.

$url = "https://github.com/$repo/releases/download/$release/$asset";

Following this scheme, I'm able to download both assets successfully.

✅ https://github.com/GatherPress/gatherpress/releases/download/0.28.0/gatherpress.zip
✅ https://github.com/GatherPress/gatherpress/releases/latest/download/gatherpress.zip

Hoping, you are able & willing to make this change.
Best regards carsten

This would be super helpful. I was just about to go this route for my upcoming WP Dev Blog post and I wanted to utilize a Blueprint that references my latest release. 🚀
