PRs created by the weekly lockfile update workflow use GITHUB_TOKEN via
peter-evans/create-pull-request. GitHub does not trigger pull_request
workflows for PRs created this way (to prevent recursive loops), so CI
never runs and the all-green required check blocks merge.
Fix by adding workflow_dispatch to the CI workflow and dispatching it
from the lockfile update workflow after creating the PR. GitHub exempts
workflow_dispatch from the GITHUB_TOKEN event suppression, so CI runs
on the PR branch's HEAD commit and satisfies the required check.
Also reverts the ref input added to shared.yml (no longer needed).
