* build: use build workflow id instead of build number.

The workflow id is unique across the whole workflow
while the build number is unique to every job in the
workflow. This change means that jobs that build
artifacts for the same commit but in different jobs
will now have the same id.

* build: fixes pkgver generation.

alerting: increase default duration for queries

no suggestions are presented at all.
