chore(docs): Delete packages/fxa-content-server/docs directory

Because

• This all exists in the ecosystem docs.

Shane wrote an updated version of the architecture doc: https://mozilla.github.io/ecosystem-platform/explanation/content-server-architecture
And I moved query parameters: https://mozilla.github.io/ecosystem-platform/relying-parties/reference/query-parameters

This pull request

• Removes the old docs

Is Current as of Nov 17th, 2022 accurate at the top of the new query param page?

Thanks for transferring!

I put that on there because it was the last date the page was updated on github. Honestly, I'd like to review some of those params. disable_local_storage ? automatedBrowser ? why would we have these things?

[LZoog]

@clouserw we do have disable_local_storage for testing purposes (unit and functional), if you search the codebase you'll see a couple comment scattered about. I don't think we need automatedBrowser with Playwright though. We'll definitely have these all double checked by the end of the React project.
