Update - July 1, 2021
Far Cry 5's fan-made GoldenEye 007 levels are back online. After a copyright claim by MGM saw Ubisoft remove them last week, user Krollywood revealed they had backups available and now, these levels have returned to PC and PS4, with an Xbox One version planned later on.
It's highly likely they'll be removed again, so act quickly if you want to access them at all. On PC, these are found by searching "Golden Cry" (Thanks TechRaptor). As for the PS4 edition, you'll instead need to search for a creator called Perfect-Dark1982.

When you include a level editor within your game, it's not uncommon to see fans try and recreate other games inside of it. Goldeneye 007 was a recent example and a YouTuber named Krollywood recently recreated all 18 campaign levels. Despite some exceptional work, they've now been taken down.
Speaking through YouTube comments on his videos, Krollywood advised that James Bond rights holder MGM sent Ubisoft a cease and desist letter, one which Ubisoft promptly complied with.

Taking this one step further, Krollywood revealed the full letter he'd been sent by Ubisoft explaining this takedown, confirming:
On 6/23/2021, we received a notice from Metro-Goldwyn-Mayer Studios, Inc. (“Complainant”) that Complainant believes the Goldeneye fan made mod in FC5 (detail below) infringes its intellectual property rights. In particular, Complainant believes you are infringing its copyright and trademarks
Comments from Complainant: It has been brought to my attention that your company currently hosts a remake of the 18 levels of the “GOLDENEYE 007” (1997) videogame crafted by Krollywood in the Far Cry 5 Arcade Mode. Exploiting our Bond Properties whether by you directly, or by a third party user, is unequivocally not admissible nor protected. Krollywood’s GoldenEye 007 remake makes unduly use of our trademarks, US TM No. 2957173 (GOLDENEYE) and EUTM No. 2045473 (GOLDENEYE Stylized and Design). Further, the cited remake inescapably benefits from our famous 1995 motion picture of the same name, protected under U.S. Copyright registration No. PA 1-397-651.
User Krollywood is not authorized to use any JAMES BOND/007 indicia, much less provide a video game to the public using your in-game map editor as the driver. In doing so, Krollywood develops an implied association to the Bond franchise. Kindly note that only the MGM Parties are authorized to grant licenses to third parties on the JAMES BOND properties thus, this misuse of our IP generates confusion among the public as it gives the impression that Krollywood’s remake is a licensed collaboration with Ubisoft and thus constitutes an act of free riding on the prestige of our franchise. I appeal to you to immediately remove this content from your servers and relinquish any and all public access via all pertaining gaming platforms (i.e. PC, XBOX ONE, PS4 and Amazon Luna).
It's disappointing considering how much effort Krollywood put into this, who previously advised they'd spent three years recreating these levels. While there's obviously a legal element at play, this is certainly a major letdown considering Goldeneye's not available on modern platforms. Thankfully, Krollywood confirmed they've got backups of these levels, so their hard work isn't completely lost.
