Subject: [PATCH 1/2] workflows/labels: skip for staging-next / haskell-updates
 / python-updates

Labelling those PRs is more annoying then useful.

Subject: [PATCH 2/2] labels: add workflow related labels

This adds some labels related to the higher level workflows of
developing nixpkgs:
- "4.workflow: backport" can be used to filter everything targeting the
stable branches, both release-XX.YY or staging-XX.YY.
- "4.workflow: package set updates" can be used to filter the
haskell/python package set PRs. Can be combined with "6.topic: haskell"
or "6.topic: python".
- "4.workflow: staging" can be used to filter for all staging-next PRs,
both to master and release branches.
