[DOC] - Track miscellaneous documentation tasks

[pavithraes]

Preliminary Checks

• This issue is not a question, feature request, RFC, or anything other than a bug report. Please post those things in GitHub Discussions: https://github.com/nebari-dev/nebari/discussions

Summary

We're working on many docs pages simultaneously. This is a broad issue to keep track of tasks that might be blocking PRs from getting merged, but can be completed at a later date.

Feel free to add comments here as things come up!

Steps to Resolve this Issue

• Link to the advanced configurations page about nebari-config.yaml in the cloud provider specific how-tos (2nd point under Nebari initialize). It currently links to qhub.dev. And, update output from QHUB_DEFAULT_PASSWORD to Nebari if/when that change is made.
• In How-tos, "Configure Keycloak" and "Authenticate using Keycloak and launch your server", we need to add links to advanced configuration pages/sections when it's merged. The links should be added where we have text wrapped by square brackets.
