fixup! Add a GitHub workflow to monitor component updates

The `environment` keyword makes GitHub Actions believe this is a deployment
environment [1], but we aren't deploying anything in this workflow. Having
a "deployment" workflow on a frequent schedule causes some pull requests like
[2] to become filled with thousands of "dscho deployed temporarily to
monitor-components" messages. This was originally intended to allow this
workflow to open issues, but we can instead just specify that the workflow
should run with permissions to create issues and then use the generated
access token.
