Perform migration from Drupal to Hugo in prod

Following up from #158, I need to track the deployment process so I don't forget a step. - [x] Back up everything on existing www.jeffgeerling.com Droplet - [x] Change every reference to `new.jeffgeerling.com` to `www.jeffgeerling.com` in Hugo and Ansible repos - [x] Merge local hugo project directory into this project's `master` branch (no need to preserve history on my local working branch—it's a disaster :D) - [x] Set Cloudflare into caching mode / 'Always online' - [x] Rebuild www.jeffgeerling.com Droplet from new Ansible config (static site only) - [ ] Deploy Hugo site to production Droplet - [ ] Set Cloudflare into normal mode and test, test, test - [ ] Make sure any new posts between Dec 28 and `time.now()` are added to the Hugo site - [ ] Delete `new.jeffgeerling.com` droplet and DNS configurations once site is migrated to `www` - [ ] Monitor logs for frequent 404s, that sort of thing (error.log especially) (maybe w/ [goaccess](https://goaccess.io)) - [ ] Check Munin to make sure stats are still loading in - [ ] Test backup of new site to make sure that's also working Once the site is deployed, here is some representative content for migration testing: - https://www.jeffgeerling.com/blog/2023/how-raspberry-pis-are-made-factory-tour/ (spaces in image filenames) - https://www.jeffgeerling.com/blog/2013/migrating-style-and-script/ (content was cut off) - https://www.jeffgeerling.com/blog/2013/how-redirect-user-after-login/ (runon sentences, php embed) - https://www.jeffgeerling.com/blogs/jeff-geerling/fixing-ssh-unknown-error-when (redirect) - https://www.jeffgeerling.com/blog/2010/monopoly-vector-design/ (download .ai files)
