[cd build]commit message to upload wheels to the staging repo=> now just merge the PR
=> to improve: remind to merge in "rebase and merge" mode in this checklist
! github limits it to PRs with < 100 commits. Otherwise has to be done locally and pushed directly
=> now done in scikit-learn-release as well
