Subject: [PATCH] Partially revert "ci: remove license check jobs from the
 workflow file."
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This partially reverts commit 39db2953db21b0239de681c5a11f689da503a67d,
i.e. revertes the 'license' directive. Without this change, the "Check
dependencies for licenses" check remains in state "Expected — Waiting
for status to be reported".
