How can I change the location of the Snippets admin menu?

You can change the position of the Snippets menu with a functions snippet like this one:

add_filter( 'code_snippets/admin/menu_position', function () { return 20; } );

You can change 20 in the code above to move the menu higher or lower than the default.

Keep in mind that you will need Code Snippets v3.2.3 or later to use this functionality.
