Run dependabot (#800)

* fix(ga): Add GitHub Actions workflow to manually trigger Dependabot.

- Created a new workflow file `.github/workflows/run-dependabot.yml` to allow manual triggering of Dependabot using the `workflow_dispatch` event.
- Configured the workflow to run Dependabot for GitHub Actions updates.

* fix(ga): A mapping was not expected

* fix(ga): Unexpected input(s) 'package-ecosystem', 'directory', valid inputs are ['alert-lookup', 'compat-lookup', 'github-token', 'skip-commit-verification', 'skip-verification']
