This commit updates URLs to prefer the https protocol. Redirects are not followed to avoid accidentally expanding intentionally shortened URLs (i.e. if using a URL shortener).
# Fixed URLs
## Fixed Success
These URLs were switched to an https URL with a 2xx status. While the status was successful, your review is still recommended.
* [ ] http://projects.spring.io/spring-cloud with 1 occurrences migrated to:
https://projects.spring.io/spring-cloud ([https](https://projects.spring.io/spring-cloud) result 301).
Not sure if it is an omit - but linking to https://projects.spring.io/spring-cloud gives an `unknown domain: projects.spring.io` error. Changing it to http url works.
