Hi team,

With the port of the Agent Key Polling module to the Authd module, Wazuh´s needs to be updated to remove the outdated references to the Key polling module and add the needed references to the Authd documentation.

The main points to cover include:

• [x] Modify the description, the general diagram and the section How it works.
• [x] Remove the agent-key-polling references in wazuh-modulesd and add them in authd.
• [x] Modify the configuration with the one added in authd.
• [x] Remove agent-key-polling configuration reference .
• [x] Updated redirects.js

Checks

• [x] It compiles without warnings.
• [x] Spelling and grammar.
• [x] Used impersonal speech.
• [x] Used uppercase only on nouns.
