Add the ability to link a Hudu Article to our own Repository

Instead of reinventing/recreating the wheel with our Hudu Documentation, it would be great to be able to reference the Hudu documentation directly within our articles in an iFrame.

An example of this is setting up OTP for M365 Accounts.

https://support.hudu.com/hc/en-us/articles/11416926227863-Step-by-step-guide-on-using-the-Hudu-OTP-Generator-on-Office-365-Admin-Accounts

Right now, when we try to setup the iFrame, it doesn't resolve.
