PR enables strictNullChecks and fixes all the existing violations.
When a troubleshooting entry is created or updated in this repo, sync it to GitHub. This creates a new troubleshooting discussion if one does not exist, and updates the content on an existing troubleshooting discussion if it has changed.
To preserve the connections between GitHub discussions and Markdown files, record the discussion ID and URL to the database. The database ID is then written to the Markdown file, and a new PR is generated to commit the new Markdown with ID.
There is currently no mechanism to delete outdated discussions. That will be a follow-up.
