HEAD no longer resolves to the main branch

[SMillerDev]

Homebrew uses the HEAD alias in the install URL, but that appears to have stopped working. Was this intentional?

E.g. https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh was returning the same as https://raw.githubusercontent.com/Homebrew/install/master/install.sh until recently.

This also breaks github.dev. If you try to open it from the main branch it tries to resolve HEAD and closes after getting a 404

I found the culprit (look no further) and I'm working on a fix right now.

Other potentially affected URLs with other symrefs like HEAD@{5}, e.g. https://github.com/nodejs/node/tree/HEAD%40%7B5%7D/src

Issue to follow up and to add tests to prevent it happening in the future: https://github.com/github/repos/issues/1143

Fix is now deployed to dotcom. 🎉
Tested successfully with reported URLs.
