docs: Add FAQ entries for Multisite, locked-out users, and role enforcement

[masteradhoc]

What?

Adds three missing FAQ entries to readme.txt.

Why?

Checked a few support requests lately that we've had. The FAQ section lacked answers to several commonly asked questions. Users and site administrators frequently ask about Multisite compatibility, how to recover a locked-out user's account, and whether 2FA can be enforced across all users or roles. Without these entries, users are left to search the support forums or GitHub issues for answers that could be surfaced directly in the plugin docs.

How?

Three new FAQ entries were added to the == Frequently Asked Questions == section of readme.txt:

• Does this plugin work on WordPress Multisite? — Confirms compatibility and clarifies that 2FA settings are stored in user meta (making them valid across all network sites), while noting there are no network-wide enforcement settings.
• How do I disable 2FA for a user who is locked out? — Walks administrators through disabling 2FA via the user profile editor or WP-CLI.
• Can I require 2FA for all users or specific roles? — Explains there are no built-in enforcement settings, points developers to the two_factor_providers_for_user filter, and references issue Enforce 2FA #255 for the native enforcement feature request.
