chore: Reorganize develop docs and change sidebar ordering

[markstory]

DESCRIBE YOUR PR

The develop docs organization has grown organically and could benefit from some more cohesive organization. The new top level directories roughly map out to:

• getting started : for general information on philosophy and inclusive language
• development : getting sentry working locally, contributing code an working with local development services.
• application : application design and architecture documentation.
• frontend : frontend documentation - unchanged
• backend : I've moved a bunch of documentation here. Previously 'services' was used for both application services and standalone applications (services) that compose sentry. Now backend contains everything you'd find in the python monolith, while 'services' contains standalone applications.
• services : services we operate that exist outside of the monolith
• integrations : unchanged
• sdk : unchanged
• relay : unchanged

I spaced most of the pages out by increments of 10 as it was easy to count and left holes for future docs to be added.

Big THANKS for investing some time in improving our develop docs! I noticed that you haven't set up any redirects, could you add them for the pages you've moved?

You can add those to this file:

sentry-docs/redirects.js

Line 4 in cbd9baa

const developerDocsRedirects = [

[stephanie-anderson]

Is this new line intentional?

[markstory]

Nope, that was a mistake.
