Add multi factor authentication for XWiki default profiles

The lack of multifactor authentication (MFA) increases the risk of unauthorized access to systems and sensitive data.
Without MFA, accounts are solely protected by passwords, which can be easily compromised through phishing,
brute-force attacks, or credential leaks. This vulnerability can lead to data breaches, and regulatory non-compliance.
Implementing MFA significantly enhances security by requiring an additional verification factor, reducing the likelihood
of unauthorized access.
