chore(build): create empty commit

and, once it's tagged, move the release-1.36.x branch there.

We created the release-1.36.x branch too early, so the [2.36.0 build](https://github.com/spinnaker/front50/actions/runs/11925822078/job/33238616660) failed:

Run BRANCHES=$(git branch -r --contains refs/tags/v2.36.0)
BRANCHES is '  origin/master
  origin/release-1.36.x'
NUM_BRANCHES is '2'
exactly one branch required to release front50, but there are 2 (  origin/master
  origin/release-1.36.x)
