Update README.md

Reference: activeadmin/activeadmin#3803

I've been using it with older versions of ActiveAdmin (0.6.x and some along the master branch). What was the bug and when might it have been introduced? I don't want to mislead new users of the gem on which version is required.

[supremebeing7]

Hm, I'm not sure when it was introduced. I've been on 1.0.0.pre since coming to this project. I understand your concern. I can try to research a bit and try to nail down when the bug was introduced. If we can't figure that out, would it be worthwhile to change the wording in this PR? Something like "If you experience issues with drag and drop, you may need to specify the version..."

I found this: activeadmin/activeadmin#3776 (comment)
Which makes it sound like this error is sporadic (which is the best kind of error 🎉 ).

I also found this: activeadmin/activeadmin#4198
At the end, one of AA's maintainers says that the fix was backported to v0.6.6.

Either of those could be why you haven't experienced this error. Either way, I think just changing the language in my edits like I suggested above might make the most sense. Let me know what you think, or if you don't think README edits are necessary.

Agreed, I think a wording update would be wise. Providing this warning could help others avoid similar issues.

[supremebeing7]

Updated wording. Let me know if anything else is needed.

Thanks for the great gem, hopefully this saves someone else some head-scratching.

Thanks!
