feat: align outline utility classes

[Techassi]

#593 (comment) mentions to adjust the outline utilities. This PR aligns them.

Examples

.outline-2 {
  outline-width: 2px;
}

.outline-red-500 {
  --tw-outline-opacity: 1;
  outline-color: rgba(153, 27, 27, var(--tw-outline-opacity));
}

.outline-red-800\/50 {
  --tw-outline-opacity: 0.5;
  outline-color: rgba(153, 27, 27, var(--tw-outline-opacity));
}

.outline {
  outline-style: solid;
}

.outline-dashed {
  outline-style: dashed;
}

.outline-offset-1 {
  outline-offset: 1px;
}

.outline-offset-2 {
  outline-offset: 2px;
}

/* Backwards compatibility */
.outline-opacity-50 {
  --tw-outline-opacity: 0.5;
}
