[2.x] - Remove unnecessary classes

[juno-w]

transition utility-class has duration-150 and ease-in-out properties by default. Therefore single transition utility-class produce the same thing as before unless different duration and easing being used.

@driesvints Sorry, this PR just removing the classes unlike the previous one.

I have checked Tailwind v1.x transition class doesn't have transition-duration and transition-timing-function properties included by default.

@juno-w this package uses Tailwind v2, not v1
