[v-select] `dense` not replaced with `density="compact"`

[phoenix-oes]

v-list, for example, can --fix dense to density="compact" but that does not appear to happen with v-select

It would be a bit of a challenge... We'd need a custom replacement function that adds density="compact" and :list-props="{ density: 'compact' }". I don't feel strongly about this, so it is left for the community to figure out a PR.
