Merge all articles related to "error response handling"

[javiereguiluz]

Let's create a single resource for anything related to "handling error responses". We could do this:

1. Merge this when ready -> [Security] Clarify the purpose of access denied handler (and entry point) #14045
2. Create a new article How to Customize Error Responses which merges https://symfony.com/doc/current/controller/error_pages.html and the article created in 1.
3. The new article should explain:
   • How to quickly customize error pages (404, 500, etc.)
   • How to customize the logic that handles error responses (401, 403, etc.)
   • How to do everything in traditional HTML responses and (JSON) APIs too.
