Update links to new examples location

The examples location in kogito-examples has changed. So, we need to review all the links on the KIE blog and in the following repos:

• https://github.com/kiegroup/kogito-runtimes
• https://github.com/kiegroup/kogito-examples
• https://github.com/kiegroup/kie-docs/tree/main-kogito
• https://github.com/kiegroup/kogito-docs
