Clarify if Installation Guide is aimed at Development or Production use case

### Describe what's missing in our docs

Address in the guides directly when you should consider this option (aka dev or prod)

Start with the Installation Guide and related guides in the Kestra docs repository. Check where the option is introduced and clarify whether it is intended for development or production use; done means the guides explicitly state when to choose each use case.
