[Feature Request] Pass <v-data-table> rowProps to <tr> inside expanded area too

[simionato-mobisec]

Problem to solve

If we add to a data table the following rowProps:

const rowProps = {
  class: ['foo', 'bar', 'baz']
}

The rowProps should be passed to the

inside the expanded area too, otherwise we have to manually add them.

Proposed solution

Pass the rowProps to the expanded rows too.
