docs: apply consistent title case across headings

Use Chicago-style title case: capitalize first/last word and all major
words; lowercase articles (a, an, the), coordinating conjunctions (and,
but, or, nor, for, so, yet), and prepositions regardless of length
(with, from, after, between, across, etc.).

Also fix the "Mode :" / "Emulation :" stray spaces before colons in
extension-workers.md, capitalize "User" in the parenthetical, and
title-case "Real-Time", "PHP Config", and the lowercase "packages"/
"binary" / "Component" / "using" cases that slipped in.

 If you plan to share your extension (like a generic queue or event listener), you should wrap it in a Caddy module. This allows users to configure the script path and thread count via their `Caddyfile`. This requires implementing the `caddy.Provisioner` interface and parsing the Caddyfile ([see the frankenphp-queue Caddy module example](https://github.com/dunglas/frankenphp-queue/blob/main/caddy.go)).
