	Purpose: Downloads and installs the latest available Microsoft
	product specified directly on the client. This avoids having to
	manually download and store an up-to-date installer on a
	distribution server every month.
	
	Instructions: Update the linkID value to one of the corresponding
	Microsoft products in the list and optionally update the sha256Checksum
	value with a known SHA 256 string. Run the script with elevated
	privileges. If using Jamf Pro, consider replacing the linkID and
	sha256Checksum values with "$4" and "$5", entering the ID as script
	parameters in a policy.

Thanks, @dmmueller! I compared the two installer packages using Suspicious Package, and it appears the link I have downloads an Intel only installer from October 2023 while your link downloads a recently updated universal installer. I've added your link and left the old one with that detail. I'll likely remove the old link later.

By the way, @dmmueller, be sure to download the latest version of the script from here:
https://gist.github.com/b6637160b65b751824943ede022daa17

I had to create a new gist a while back for reasons. I've added a noticed at the top too.

Gladly! @talkingmoose, I wonder what other IDs they may have modified?
