Design method to communicate MS build info to SB partners

In order to collaborate with our distro partners and enable their daily CI workflows, we need ways to communicate information about Microsoft's builds. For released builds, we have a [release.json](https://github.com/dotnet/dotnet/releases/download/v10.0.0-preview.4.25258.110/release.json) that is added to the release info on GitHub, which distro partners can use to determine how to launch their builds. This doesn't work today for a rolling CI though.

We need a way to resolve this. Requirements:
- Should be possible to draw a line from a sha of dotnet, to the build settings if there was a successful build
- Multiple builds of a sha should be supported.
