fix: Separate Example Applications and SDKs/Integrations more clearly (#11569)

# Which Problems Are Solved

The distinction between Example Applications and SDKs has not been
clear. In the SDKs section a lot of Example applications where listed.
Also In the SDKs it was not really clear what the SDKs actually are.
Also some examples and skds are outdated and not well maintained
anymore.

# How the Problems Are Solved

- Moved all example app guides to the Example Applications Section
- Restructured SDKs Nav --> SDKs & Integrations: Frontend & Mobile,
Backend & API, Management API Clients
- Removed unnecessary / outdated guides
- Remove ids in framework.json for frameworks which shouldn't be
rendered in console

## Todos:
- Update SDKs Introduction page
- Add links to common oidc libs for most used frameworks
