Windows

Describe the bug

When a shortcut for an instance, which contains a dot in its name, is created, the shortcut name will be wrong, skipping all the text after the dot.
In the Windows save file window, the name appears correctly, but hitting Save and looking at the real shortcut, we can see that is wrong. This happens because Windows thinks that the text after the dot is the format extension.
Here it is an example:

Steps to reproduce

1. Create an instance with a dot in its name, rename it, or go to one that has a dot.
2. Click More actions.
3. Click Create shortcut.
4. Click Save on the Windows popup.
5. Go to the location where the shortcut has been created.
6. See the wrong name.

Expected behavior

The name of the shortcut after saving it on the Windows popup should be Modrinth - <instance name>, without skipping part of it after a dot.
