Wrong value given to the custom directive in migration guide #632
Description
In the example given in the migration guide concerning the custom directive hooks with Vue 3 syntax, we see the following example :
<p v-highlight="yellow">Highlight this text bright yellow</p>
which cannot work because it will raise the following error :
[Vue warn]: Property "yellow" was accessed during render but is not defined on instance.
the correct value should be done as string or the yellow value should be defined as property :
<p v-highlight="'yellow'">Highlight this text bright yellow</p>
