Some remote devlopment doc comments
When trying to set up a K8s cluster for Remote Development, I experienced several issues with the docs. Examples:
* missing brew install commands when certbot is throwing Python errors, brew install python-certify was required
* brew dedicated to Mac users only, Windows and Linux missing
* when using helm and it is related to GCP, glcoud commands and auth-plugins needs to be installed as well
* referencing the architecture from the workspaces setup would be helpful to better understand which part of the diagram one is implementing with the instructions (as there is a lot to configure the overview is difficult)
* I would appreciate the required know-how was listed somewhere; K8s, DNS entries,
* I wonder how to handle the need to apply the very own certs of an org
* reusing nginx versions that are to old
* explaining the potential error message when the dns_zone is having a bad formatting like \<\> were accidentally copied
