Add default transition-duration to transitionProperty utility

[fedeci]

What do you think about adding a default transition-duration to the transitionProperty utility?
This would reduce code repetition because this would become available:

...
<!-- transitionDuration set as default value to 250ms -->
<div class="bg-red-700 hover:bg-blue-700 transition-colors w-10 h-10"></div>
...

But in case of need it could be overridden using duration-x:

...
<div class="bg-red-700 hover:bg-blue-700 transition-colors duration-150 w-10 h-10"></div>
...

And the code generated would become something like this:

.transition-none {
  transition-duration: 250ms;
  transition-property: none
}
