delete authenticate as its own how-to chapter

another item on the Cookbook reorganization: delete Authentication chapter and reminder for earthaccess

I was thinking that instead of deleting this section maybe we should update it and move it to an appendix. Authentication with Python is semi trivial with earthaccess but people sometimes use lower level APIs and they need to know how the internals work, e.g. cloud vs on-prem.

Ah, an Appendix is a good idea so that alternatives can live there but we can still have our opinionated approach.

Hi @betolink , picking up this thread - I've moved the authentication.md file to the appendix. It still needs to be updated with the current preferred approach but I wanted to help with the quarto architecture

Looking good!
