Consider special-casing properties where slash-separated numbers are common

[jathak]

The division migrator errs on the side of overcorrecting /-separated values to math.div, since math.div still supports concatenation for non-numerical values.

Since these values most commonly occur inside grid and similar properties, we may want to consider special-casing them in the migrator to leave them alone.

I faced exactly that issue after running sass-migrator division on my sass files.

Another edge case where / is used as a separator that triggers a migration that should not occur

.foo {
  background: repeating-conic-gradient(
      var(--p-surface) 0% 25%,
      var(--p-surface-neutral-subdued) 0% 50%
    )
-    50% / var(--p-space-4) var(--p-space-4);
+    math.div(50%, var(--p-space-4)) var(--p-space-4);
}
