Make the upgrade cli output work with v3

[remorses]

Currently the upgrade cli formats classes in a way that is no longer compatible with v3 for example replacing outline-none with outline-hidden

These changes make your classes stop working for users still using v3 which is a big problem for component libraries.

Instead I suggest keeping the classes in the format that still works in v3.

Users still using v3 could easily overcome the other breaking changes by updating their config, for example adding the theme tokens for ring, rounded-sm, rounded-xs, etc
