Emit Build Scans for interrupted builds

[DavidGregory084]

Expected Behavior

It would really be beneficial if partial Build Scans could be emitted even when a build is cancelled externally.

Current Behavior (optional)

When a build is cancelled (for example by clicking "Cancel workflow" in the GitHub Actions interface), no Build Scan is attached to the build summary:

Context

One of the most challenging issues to debug when using Gradle is builds which hang in CI.

This is compounded by the fact that when a build is cancelled externally, no Build Scan is emitted.

It would be really beneficial if a partially-complete Build Scan could be emitted on external cancellation, as this might give insight into the task which is causing the build to hang.

[wolfs]

It is quite probable that the build produced a Build Scan nonetheless. Only the tooling doesn't pick it up for the Github action, since it has been disconnected. If you use Develocity and can search for the Build Scan, it is quite probable that you find one.

I'll add this item to our backlog to see if we can do something better in that regard - aka report the scan to the user/integration even when the build is cancelled.
