+name: Rebuild Action after Renovate PR
+# cypress-io/github-action runs from the dist/ directory
+# After Renovate has created a PR that updates dependencies,
+# the built action in dist/ will be out of date.
+# This workflow ensures that the contents of this directory
+# are in sync with the source files by using
+# npm run build which in turn calls ncc build to rebuild
+# the dist/ directory
