Merge bitcoin/bitcoin#33744: ci: Fix lint runner selection (and docker cache)

Pull request description:

  Fixes: #33735

  Correct runner type selection for the lint job.

  This was erroneously left-out during refactor of the runner selection mechanism in #33302 causing the lint job to run on GH hosts (and therefore not be able to acces local cirrus caches).
