Prebuilt option for custom database script for Microsoft Entra ID

Feature: Add language specific example of custom database script for Microsoft Entra ID (previously Microsoft Azure AD)

Description: * Login Script Templates lists language specific examples for several common password storages, but not Microsoft Entra ID. While I could write one myself, I risk making security vulnerabilities while doing so, so having an official script example to use would provide peace of mind that we’re doing it correctly.

Use-case: Attempting to migrate from a shibboleth SAML login system backed by Microsoft Entra ID password storage, but now I have to write a custom database script while not really wanting to learn how Microsoft Entra ID works, since we’re moving away from it. Microsoft Entra ID is a commonly used system, and having an prebuilt way to migrate from it would come in handy.
