Enhance documentation with Docusaurus features and fix inaccuracies

Verified against source code and enhanced with Docusaurus markdown features:

Documentation Accuracy Fixes:
- Fixed acme.md: Added "letsencrypt" as valid AUTOCONFIG value (was incorrectly shown as "-")
- Added reference to ACME docs from environment-variable.md
- Verified all features against actual implementation in /src

Docusaurus Enhancements Added:
- Admonitions (:::note, :::tip, :::warning, :::danger, :::info) for important callouts
- Code block titles for all bash/yaml examples (e.g., title="Install EasyHAProxy")
- Better structured warnings and notes for limitations
- Improved formatting and readability throughout

Files Enhanced:
- kubernetes.md: Added info boxes, warnings, code titles
- docker.md: Added limitation warnings, code titles
- swarm.md: Added advantage tips, limitation warnings
- acme.md: Fixed Let's Encrypt autoconfig, enhanced requirements with admonitions
- ssl.md: Added code block titles for all examples
- static.md: Added live reload tip, SSL certificate note
- container-labels.md: Added definition explanation, code titles
- limitations.md: Restructured with clear warnings and explanations
- helm.md: Added warnings, code titles
- microk8s.md: Added ingress controller warning, code titles
- volumes.md: Added info box about volume purposes
- other.md: Added code block titles
- environment-variable.md: Added ACME reference note

All changes verified against actual Python source code implementation.

+:::info Understanding Definitions
+The `[definition]` is a string identifier that groups related configuration labels together. Different definitions create separate HAProxy configurations.
 
-The container can have more than one definition.
+A single container can have multiple definitions to expose different services or ports.
