The GIMP 2.10 shortcuts are all stored in a single file that sits in the GIMP user config folder, called “menurc“. In order to change them, you only need to replace that file.
An important note is that the previous GIMP versions have a different path, which I am not covering here because anyway I believe very few people, if any, are using them anyway.
In Windows 10, the path is: “C:\Users\{YourUserName}\AppData\Roaming\GIMP\2.10“.
The file that has the Photoshop shortcuts can be manually downloaded from here. Then you can just copy it to that folder with overwriting the existing one.
NOTE: The GIMP program needs to be closed before doing this.

Alternatively, you can open a Powershell command/terminal and just paste this code line, which will automatically do all the job for you, including taking a backup of the original “menurc” file, just to be on the safe side:
cd $Env:UserProfile\AppData\Roaming\GIMP\2.10; mv menurc menurc_bck; iwr -outf menurc https://www.webcreative.me/wp-content/uploads/menurc
