Improve 🧂 SonarQube default admin password

[kareiva]

Let the SonarQube out-of-date warning go away.

This should be safe to merge, tested locally, and docsify renders it nicely.

Then we can bump the sonarqube version here or somewhere in between: redhat-cop/helm-charts#659

Tested ✅ on cluster-dqn7k.dqn7k.sandbox3357

The password needs to fulfill the following requirements: at least 12 characters and contain at least one uppercase character, one lowercase character, one digit and one special character.

So I have picked _ as the safest-possible choice (+ and # do not work as they are not URL-safe)

Hope it makes sense. 🤞

I just left a comment at the helm chart repo, @kareiva. And is there any screenshot changes needed in the chapter https://rhoai-mlops.github.io/lab-instructions/#/8-the-supporting-acts/4-code-analysis? thanks!

This can be merged independently from the helm chart repo. And until then, it actually requires no screenshot updates. I have tested it with the current version and it's backwards-compatible.
