Tie list of allowed domains for embedded links to more software providers

[lyndoer]

Is your feature request related to a problem? Please describe.
Yes. The list of allowed domains for embedded links is relatively short and favors Google-affiliated software. It needs to be expanded, particularly to Microsoft-affiliated software because we are required to use Microsoft! For example, we can't embed our email list sign up on Mass.gov because there are no email marketing services that can be embedded. The solution provided is to use a formstack form and translate them over to the email marketing which is a waste of time and energy and the process can be easily lost with turnover.

Describe the solution you'd like
Include Microsoft-affiliated domains on the list and expand the list to include more service providers.

Additional context
Examples where I require the ability to embed links include PowerBI and EMMA (email marketing). Although all commonly used email marketing services in the state should be included.
